the 70D looks much more better in terms of image results compared to the 60D or 7D... i like its sharpness :)

I'd be very hesitant to draw a final conclusion from these b&w res charts w/o knowing the tradeoff, either more aliasing or noise.

Plus since nobody saw that sharpness increase in previous studio sample shots vs. the 18mp sensor, it's possible Canon came up with some way to "enhance" the edge contrast even in raw, maybe in combination with the dual af pixels, it's a consumer camera after all so some "tweaking" is allowed.

It could be real though. It could be a change in the AA filter and/or also the greens in the CFA might be so extremely split as they on the 7D so RAW converters can get better acutance out of the files without running into mazing issues. If you compare 7D files developed with the original beta RAW support in ACR or even Canon's own DPP they have a bit better acutance than when using release versions of ACR or later DPP versions. But the earlier RAW converters also left 7D files riddles with "mazing" artifacts all over which is why they had to be changed.

Agreed, it is very sharp, but doesn't exhibit much in the way of aliasing. Quite a bit sharper than the 7D, too.

Everything on the left of the 32 mark is aliasing (the converging lines on the top). Other sensors do that, too, to a different extent.
