Retirement makes an interesting distinction, though it will probably take a couple years for it fully take hold of your life... Business success is not required, only personal success... and that applies equally to amateur and professional photography.
You hint broadly at the potential to become very serious about photography. I won't address that decision, and instead will comment of the significance of deciding that is in fact what you will do. If you haven't, and don't, decide that is where you are heading, then my comments might not be applicable.

I have these lens: Nikon 55-300 AF-S f/.4.5-5.6G ED VR DX: Nikon 55-200 f/4.0-5.6 ED Dx and Nikon 18-55 f/3.5-5.6G VR AF-S.
Consider all of them temporary substitutes until they can be replaced, and do not weigh them at all in deciding on a camera body.

Wildlife, birds, and sports always seem to require a longer focal length lens than whatever we have. Vacations and landscapes aren't extra ordinary for lenses. But grandkids almost always means some kind of "event photography" which will include poorly lighted school gymnasiums and auditoriums. That means cameras with low noise at higher ISOs and f/2.8 zoom lenses.
Event photography, even with today's technologies, just about requires the top of the line cameras and lenses to do it justice.

Another fascinating bag of worms! Check out the Epson 7890 printer. If you have the where with all (time, space and money), and feel it would be worth it, I'd be happy to share my experiences on that topic too.

I've looked at the Nikon D7100 and the 810 looks interesting. Knowing myself well image quality will be important. All comments are appreciated, including those on comparable Canons which I've not explored yet.
Canon isn't really in the running these days.
I use a D4 and a D800. The D800 gets about 75 percent of my work, but frankly if I could only have or the other I would have to take the D4. Sports and event photography are a step above with a D4.
If and only if you just can't justify the budget for at least a D800, would I recommend the D7100. That said... for the price the D7100 is an astounding camera for image quality. It's just that for convenience and functionality a D800(E), D810, D4 or D4S is worth the extra cost for serious work.
But the cost does start adding up. With any of those cameras, if you do sports and event photography to get shots of the kids, a 70-200mm f/2.8 VRII is all but essential. The original VR version, or maybe the Tamron 70-200mm might be okay if you choose a D7100. The Nikkor 24-120mm f/4 makes a great walk around lens. If landscapes or the like are very important to you, then other lenses such as one of the wider zooms and/or the 24-70mm f/2.8 may be very useful.
For wildlife, birds and sports you might also want to look at something longer. The Tamron 150-600mm zoom seems to be a fantastic lens. The Tamron's longer focal length is better for wildlife and birds, but the shorter range of an 80-400mm is missing with either the Tamron or with a 1.4x TC on the 70-200mm. How important the shorter or longer extent of these zooms might be depends on your needs and is hard to predict until you really get into it.
