I'm waiting for the Canon 12Z Mark9, with onboard Mac OS, 6" retina display LCD, and octo-card support (triple CF, triple SD, 1 microSD, and 1 nanocard [not yet invented]). It will have a direct link up to the Hubble space telescope for snapping shots of nebulae from my bedroom. It will definitely have a 10TB wireless network connection to mah laptop, and 250,000mah LiPo batteries for continuous use. And if it doesn't shoot at 49 FPS... I'm throwing it on the ground and waiting for the Mark10. Oh, and the sensor better have 790megapixels, or I won't even look at it.
5DMark3? When you compare it to the specs I've listed, you realize that it is a total joke of a camera. I don't know how photographers get by with such junk.
