Everyone says that the Canon 7d is better at video, and I believe it must be so. But I find it unpersuasive that the reason is 1080p versus 720p. Likewise, I find it unpersuasive that 18mp is better than 12mp. Canon CUT the mp of the G11 from the G10 to increase quality. Nikon's current flagship pro camera (D3S) is 12mp, and we know the 7d's 18mp aren't better than that. Broadcast hdtv is 720p and those sports events look pretty darn good as is. I'd certainly be happy with that quality. What are the RELEVANT reasons that make 7d better at video? If 1080p is relevant and I am missing the boat then I'd appreciate an explanation why. Thanks,
