What was the point of stuffing 18MP on an APS-C sensor and making it produce big, noisy, blurry files from lenses not designed for such a high pixel density, with no more detail actually resolved than with a 10MP sensor and becoming diffraction limited at f/6-7?
Could they not instead have given us an 8-10MP sensor with much better dynamic range, ISO 6400-12800 with well-controlled noise and capable of shooting 16fps (9MP shooting at 16FPS would have the same amount of data moved as 18MP at 8fps)? Surely the pro/prosumer market (particularly wildlife photographers) that this body is presumably aimed at understand that megapixels aren't everything...
If this is true, it's a real disappointment, given that Canon recently reduced the pixel density on the G11 as compared with the G10...
