Hope they annoucement will bring smth which let me stay with canon. Otherwise i will go back to my trusty old friend nikon. I really keep my fingers crossed for good af, better built quality, slighty better iso and better dynamic range. A lot of expectations to meet, i know but i wait a long time to see what both companies finally bring. I was not happy with 5d2 but have invested already a lot in lenses, so for me the annoucment will be almost a a decision maker, hope the first reviews will come asap.
