This camera looks freaking awesome! Wow! I can't wait! If Canon didn't release this I was gonna buy a Nikon D90
Checkout DP Review for a general review and as soon as I have one I'll let you guys know how I like it.
It's such a funny game that Canon and Nikon play b/c Canon has had the ability to do all this stuff for awhile but since Nikon, being a smaller company can't develop as fast Canon just waits and then whenever Nikon releases something good Canon releases something a little bit better. I know everyone gets crazy about Canon/Nikon Mac/PC Raw/Jpeg and I think it's funny b/c both companies have really good cameras but Canon will always be the leader now that it's a technology game.
