I've been A Nikon shooter since 1970, and I own A Nikon D800 at present, that I purchased new.And I own the holy trinity of Nikon lenses and then some.... I"m think about upgrading to a Nikon D5, or should I wait for its successor ?? what are your thoughts??
I have a D800e and a D5 (and a D4). The D800e is a very capable camera for some things and the D5 is a very capable camera for other things. Different things.
My shooting concentrates on events, mostly indoors. I encounter a lot of low light situations so I'm ISO driven much of the time. I can use the D800e up to about ISO 6400, but the D5 I can use up to 20K. I generally put a different lens on each body and put two cameras in a sling bag and carry the third. That way I don't have to fiddle with lens changes during an event. I would estimate that 75% of my event shots are with either the D5 or the D4 and 25% are with the D800e.
For more casual photos I probably use the D800e more. The D800e is good at low to moderate ISO levels and has a bit more resolution. Resolution goes as the square root of the megapixel ratio so the difference is around 35%. The dynamic range of the D800e is good at low ISO, while the D5 is optimized for high ISO. The dynamic range of the D800 is greater than that of the D5 for ISO below about 2000. (see
http://www.photonstophotos.net/Charts/PDR.htm ). The D800 goes to 5 frames/second while the D5 will go to 12 (or 14 if you allow it to leave the mirror up during the burst).
Both cameras have dual card slots, so they're good for important shoots where you can do a backup in-camera. Personally, I prefer to have two of the same kind of card, but it's not really essential.
And I have the holy trinity also, but I added the 200-500 f/5.6. That gives me 14-500 for a range (but not all those lenses fit in my bag so I have to carry two). I found that the 200-500 has an up-to-date VR, which works much better than the VR on my old 70-200 (and my old 24-70 didn't have VR at all). So I upgraded my 24-70-200 and I find the VR allows me to use slower shutter speeds than the old lenses required. That could be pretty pricey if you do them both, but if you can use slower shutter speeds you can use lower ISO and more VR. In that case you might not need to use a D5 and can start saving your money for the D6.
The difference between the D4 and the D5 is significant, but not huge. I think the days of large gains in performance are behind us. Much of the gain in the D5 over the D4 is in the software/firmware. The sensor is probably pretty close to the theoretical limit in sensitivity so I wouldn't expect to see a lot of improvement with the D6. I'm not an optical engineer or software engineer so my opinion can be strongly devalued. I didn't expect the D5 to be much better than the D4, and it really wasn't, but it was enough to get me to shell out for the D5 and I'm glad I did.
