Nothing to do with any dime store novels. Many huge companies maintain a coterie of well-informed near-employees who are privy to much that is in planning. I spent a winter in Turkey with one such person aligned with Microsoft who was in receipt of software to beta-test.
Don't know where you get "second error" from? The whole point of my question is aimed at trying to establish when Canon is likely to release (say, for examply only) a 5D Mk5 so that I can take advantage of the inevitable price drop on the 5D Mk4.
Also have no idea what you mean about popularity contests? I am not asking IF a 5D Mk4 is a good purchase, I am simply trying to ensure that if I buy one at retail on a Friday I am not stunned by a new release the following Monday when my now-purchased Mk4 could be had for much less.

Thanks for that. I didn't mean physical lifespan, I meant the period of time during which the Mk4 is the premier offering in the 5D range, so that I can take advantage of the inevitable reduced price when it is superseded, as the Mk3 currently is reduced.

I read the reports on here in in my photo mags. I have a 7DMkII and now want a 5DMkIV also.

The 5D4 is a little over 2 years old and is not due for replacement soon although admittedly, my crystal ball is a bit cloudy this year 😩 (the 5D3 was almost 5 years old when updated to the 5D4). Buy the camera - I can tell you that it is an excellent body with some great features, ruggedness and performance. I just traded up my 5D3 (which was an excellent body) for one, and it’s world class.

We can only guess as I made a guess and MT Shooter made a guess and we both think it's next year. There are some people who know but if they tell you they are putting their jobs on the line.

True. I was hoping for insight, as you have provided, but not trying to compromise anyone's position. A fine line, eh?
Thank you.

I don't believe I was being condescending at all. I was simply offering clarifying information, not pretending to be superior to anyone.
Your words: " It looks like they might be moving into mirrorless cameras as a priority"
Canon has been making Mirrorless cameras since 1937 and Digital Mirrorless cameras since 1996. I included a clarification on "Mirrorless" cameras because I was referring to all Mirrorless cameras, not just MILC'S, which Canon began marketing in the summer of 2012. For some strange reason, many, many people refer to MILC'S as Mirrorless and yes, they are mirrorless, but so is the M50 and the G1X III and the SX70HS, to name a few. Canon makes a lot of Mirrorless cameras and some of them are Interchangeable Lens Cameras and a lot of them are not. All Bridge cameras and Point and Shoots are Mirrorless.

Also, I don't understand your megapixel reference. Canon's first megapixel camera was the PowerShot Pro 70 introduced in 1998. Every digital camera since the Pro 70 has been a megapixel camera.

I've been a big fan of Canon for over 40 years, ever since I bought my first Canon SLR, the AE-1.
Over the years I've acquired several Canon cameras, including the 5DIV, 5Dsr, 10D thru 80D,
6D, 7DII, G1X, II & III, a few other G series cameras and a few SX series cameras. Heck, I even have an M50. Have no plans on getting an EOS R, will wait until its replacement hits the streets. I also have 4 Canon printers, 2 Pixma Pro's and to all in ones. My laser printer is an HP.

Point is, I know a good amount about Canon because I keep up with things Canon. Also, I too am very happy with my Canon cameras, and I'm happy with my Nikon cameras also. I was happy before this conversation started and I'm happy now. And I agree with you, the 5DIV is a great camera, a solidly built feature rich high performance DSLR that I use all the time. How's that for happy.
So I know a

You can keep up on new Canon products here: https://www.canonrumors.com/ I wouldn't look at a camera purchase with the life span in mind. If you buy a new camera, it could last several years depending on how well you took care of it. Remember, it's the final product (your photos) that you need to be concerned with, not how long a camera will last for you. Cameras are like all digital products, they will constantly evolve and we will always be behind the curve. If you want to keep up with the newest products you will need a lot of $$$ to do so. Buy new equipment when your older stuff isn't working anymore or when your current equipment isn't giving you what you want.

5D II - 2009
5D III - 2012
5D IV - 2016

You can figure the 5D V will be introduced in 2020. Canon seems to like a four-year lifespan of production. As for the lifespan of the camera, a million photos would not be out of the question.

Cameras are always released before the Olympics?

If you are asking when it will be replaced by the next model of 5D, then there's only guesses at this time. Canon said that they are focusing their efforts mostly on the EOS R camera line including EF-R lenses. They are coming out with 5 new EF-R lenses later this year. So this may put the kibosh on innovative replacements for current DSLR's. They might have a new 5D V or 1DX Mark III in 2020, but I wouldn't expect a lot of big changes to them. Just a few more bells and whistles and fluff since they are putting so much into the EOS R line now....

As someone else said, the replacement 5D will probably be $3600 or so since the 5D IV cost $3500 when released.

burkphoto Loc: High Point, NC

Original 5D release: 08/22/2005
5D II release: 09/17/2008 (three years, one month later)
5D III release: 03/02/2012 (three years, six months later)
5D IV release: 08/25/2016 (four years, five months later)

The trend is for Canon to sit on new releases a bit longer each cycle. They might release another 5D (Mark V?) in about four to five years from the last one. Whether they continue the series will probably depend on the success of mirrorless gear, and the degree to which they can push either technology. The decline in dSLR sales and rate of mirrorless sales' ascension will play a huge role, too.

That's very insightful of you. I need to think through the implications to try to guess when it will translate into a lower cost for the Mk4.

Of course the risk is that when the Mk5 comes out there will be some feature or group of features that end up pushing you to get it instead...
