Can you control the camera and use live view over an eyefi card? I have no interest whatsoever in downloading pictures over WiFi.
wifi has no value to me when I shoot wildlife. in fact, unless I am shooting in a studio I can not image using wifi (I am sure I am missing some uses).
Major interest is the new sensor - multiple layer implies higher effect resolution. but what about DR? Unless Canon thinks that this camera will not be used contrasty subjects (which is not true - back lit wildlife, sports, etc).
Wildlife seems like a perfect use for WiFi. Being able to control a second camera without being right next to it is amazing. I think it's extremely regressive for all of these photographers to continually say "Well I'll never use it, so it's useless to everyone!" It's been said about GPS, flip screens, video, digital capture, programmable modes, autofocus, and basically every other feature that's ever hit professional cameras. The thing is, every time, they're wrong. Not everyone is a wedding photographer, not everyone only shoots landscapes. Theres tons of capabilities because there are tons of possibilities, and it's disappointing to see today's photographers trying so hard to stifle innovation in the name of a tradition that never seems to have really existed.
