Ok. I've decided that I'm going to upgrade my T2i in the next little bit for a full-frame camera, so the 5DII.
For a while I was leaning towards the 7D, but realized that what I enjoy taking the most are pictures that are about image quality rather than the ability to very rapidly capture a fleeting moment. To that end, I'm now looking at the 5D. I'm fine with no longer being able to use the two kit lenses I got with my T2i - I seldom to never use them anyway.
I'm getting the first bonus at work in three years in a week and a half, and might purchase the 5DII body at that time. However there are numerous indications that by Photokina 2012 there will be a 5DII successor/new FF body announcement.
I'm curious - what anticipated improvements do YOU expect from the next Canon FF body? Video is great, but I'm getting a DSLR primarily for photo.
