I'm dissapointed by those holes on the front - that doesn't look to water resistant. I will probably tape them up. Also I'm dissapointed by the 5D line seemingly still not getting a built-in eyepiece cover. That really sucks. the crappy little rubber thing they give you on the neck strap is really tacky and hard to put on, and means it's easy to lose your eyepiece, and a right pain when you have to put it on and off repeatedly. Nikon D700 has had this for a long time. 3 years wait for a glorified 7D with a full frame sensor?
Quite frankly I was hoping for more - a lot more.
