To me, this isn't so much about innovation as it is price and company focus.
I am, as I expect most DSLR owners are, a hobbyist. A serious hobbyist, but a hobbyist none-the-less and I'm not rich. I own a Pentax, which I am pretty happy with. I've been wanting to make the switch to Canon FF for about a year for several reasons (resale, used market lens availability, etc.). I have not purchased anything for my current platform since I made this decision. Having watched this site and others, studying every review I can get my hands on, watching sales and Canon's own actions, several things have become abundantly clear to me:
I have to buy a 5DIII, I actually lose functionality over my $450 K-30 by spending $2k on a 6D (to me, the crop sensor 70D is a much better buy than the 6D, even though I don't shoot video).
To do what I need to do, I need a few quality lenses and a flash. Let's price this out (rough estimates):
5DIII: $2800
600EX-RT: $450
Sigma 1.4 EX DG HSM: $500
Tamron SP 24-70 2.8 Di VC: $1300
Tamron SP 70-200 2.8 DI VC $1500
So, for just the basics, we are looking at somewhere around $6600. As a hobbyist, that's a ton of money. That's a used motorcycle, a carefully-budgeted 3-4 week dream vacation around the world, or if invested now, retiring a year early. That's asking a lot from the general (non-money-making) population.
Let's say I'm willing to do it. Should I? Well, to answer that, I look at the company, it's focus, and it's competition:
- On a technical level (dxo mark scores, etc.) Nikon is currently kicking the crap out of Canon. Because some of my "work" is astrophotography and Nikon does some noise reduction (which also wipes faint stars) prior to writing the RAW file, Nikon is not an option for me. I also realize that this is a leapfrog game, with "who's best" changing year-to-year. Canon is behind right now, are they focused on fixing this?
The 5DIII is over 2 years old but their focus has been on everything except FF: Compact updates, mirrorless cameras, and for some reason, updating many of their best/favorite lenses instead of improving the lower end ones. Outside of the Rebel line, the only rumors I've seen of an updated DSLR are for a crop sensor; the 7DII. Those rumors have been going on for at least 5 months with every rumor suggesting a release the following month, and then a delay.
So, it boils down to this:
Am I willing to scrimp, save, and spend the money? Yes, but I think it's way too much money.
But, do I really want to spend the better part of a year's discretionary income on a FF camera body that is nearly outdated for a platform from a company whose focus seems to be everywhere except non-consumer camera bodies?
Not a chance.
