Hey guys. I am almost certain that the Canon EOS XTI (400D) is the camera I'm going to get, probably tomorrow because its going on sale with two lenses and 4GB memory card. But the only reason I'm a little hesitant is because I don't want to get it and find out in a couple of months a newer model will replace it. Does anybody know where it is in its lifespan, is Canon going to be releasing a newer model soon? Thanks.
