The extra MP enable tighter cropping and looser framing so even for sports use it can be an advantage. The disadvantage is the data handling but honestly we can all handle tens of thousands of 30mp images.Rumors are rumors...i could be!
But I think the vast majority of folks using this professionally have no need for the extra MP. Keeping it lower allows the limited processor capacity that can fit in to a camera to be used for other things, more FPS, etc. 20 seems like a lot to me, but others seem to think its not enough...so who knows.
