A lot of ways to interpret this. It appears to me that the redesign of the microlens was the major focus, although what that means in terms of other necessary changes to the sensor is unknown. I certainly will withhold judgment until there are actual tests of the camera. Canon is explicitly claiming improved low-light/high ISO performance, and Kelby claims that it is the best crop camera in that regard that he has seen. Some whine that the "crop" modifier suggests that this means little. To someone who is going to use a crop camera in any case, I look forward to the possibility that this body is better than any other in its class.
The issue with a microlens redesign, IMO, is that we have seen this in the past. I think it was the 50D, in which case, the jump from 10mpx to 15mpx produced about the same amount of noise as the 40D, so the microlenses redesign helped a little to mitigate the resolution jump.
It will be interesting to see how much really is pulled out of the 70D sensor with a microlens redesign. I don't expect that to be really all that large of a hardware improvement, but time will tell. Perhaps good for 1/3 to 1/2 stop over the 70D, but still doesn't do anything for DR/shadow noise, really, as the noise floor is still going to problematic for underexposed or pushed sections of photos.
Can't wait to see this in the hands of those that really know how to do comparisons! I won't be able to be a first round adopter like I was with the 7D, there are much larger items vying their way for my bank account this season.
