Spidealex; Sorry to be a pedant, but I think you should change your video to the youtube version. The one on vimeo has simply been ripped from youtube and reposted on vimeo. It's better to link to the original video on youtube.
back on topic. The pre-order price doesn't make any sense to me at the moment as it's £1700 body only in the UK but in the US it's $1700! I think I'll end up doing what I usually do and importing one once they are available! The body saving goes a long way towards a very nice lens... which will be what really makes this camera shine.
I don't think people should underestimate the quality difference between good and bad glass. I used to do a lot of photography and have friends who are pro photographers, so I definitely appreciate a super clean fast lens. If you're thinking of sticking a 50mm f1.8 on this camera then I think you're not really doing it justice. Or perhaps it's better to say that you're not going to get the best out of it. As a starting point it works... but none of us want something that simply works, we want the absolute best thing we can afford!
