IMHO it's a wrong mentality to consider APS-C as the poor, mutilated brother of FF.
Crop sensor cameras offer longer reach and deeper DOF, which are very useful for many applications. Lens usually behaves better, especially as far as border performance is concerned, due to the sweet spot effect. Also lenses designed for crop sensors are cheaper and quite well performing:
Canon 15-85 is 30% cheaper than Canon 24-105
Sigma 17-50 f/2.8 is 35% cheaper than Sigma 24-70 f/2.8
... and so on. And all of these are very good lenses within their scopes. Most of people just buy a fast prime for portraits and other shallow dof applications. Nikon has even launched a variety of cheap yet good fast primes designed for APS-C. So basically for most users a FF is a very bad deal.
Furthermore, as many Pros as there could be, amateurs will always be more, and crop cameras are way cheaper. I guess Canon (as most companies) gets the most of its income from the lowest segments of market, which means point-and-shoot and consumer reflex cameras. In the last years we've seen the 550D bring few relevant upgrades to the 500D, then the 600D bringing even fewer to the 550D. Now Canon has the 650D on top of its priorities, and IMHO it's a consequence of the fact they've already lost the 1100D vs D3200 battle. Canon cares the least about 7000$ cameras, as they are the thinnest slice of the market, and this is why we get a new one every every 4 years instead of every 2. It's more a matter of showing muscles than of real income forecasts.
So what I mean is: crop sensor cameras are a market of their own, and all but secundary.
Nikon D7000 can rival the 7D in many aspects, yet being considerably cheaper. Canon 60D is no match, so what happened? You got a 60Da. Now we're getting a new firmware for 7D which adds new features. The question arises rather spontaneously: why at this time? Why didn't they do it sooner? It sounds a lot like "We're still alive".
Now that they have used DigicV even for the new PowerShot cameras, I think they cannot delay a refresh of the 60D/7D line too much. I am very excited because I know they'll have to beat the D7000, which is already quite an impressive camera at a very sweet price. But I also think they're having a hard time in doing so.
