I haven't seen anything that mentions an actual availability date yet for the UK. I think it's finally time to take the plunge and spend some money, I think the 7DII will end up being out of my price range at the moment. This seems like a fantastic upgrade for the 400D and generally looks like a very capable camera with some decent features.
Having not had the joys of video, live view or many of the other features, I feel this alone will provide quite the learning curve. Bit annoying that I'm going to have to go out and buy a whole load of SD cards now though! At least the wife can have the old camera and keep all the old CF's.
Other than Canon's official videos, how long would it normally be before this is in the hands of independent reviewers so that we can start to get some decent, hands-on video reviews? Written articles are all well and good, but my patience for some of them runs out pretty quickly!
