Now that the mega-pixel race is slowing down, and people aren't quite so impressed by more, more, more, and both companies now have both a full-frame pro body and pro-sumer body, what's the next big innovation for these two going to be? I'm not talking about a slightly faster FPS count, or marginally improved high ISO performance, but something big. I've been thinking about this for a little while now, and I'm thinking it's got to be in-body image stabilization. Anyone agree? Disagree? What do you think?
