I attended an Olympus open day at a studio in Glasgow where I was able to use the new d-1 for a couple of hours.
Handles nice, af is very very fast and very very accurate (it was quite dark, although I was using fast lenses with single point af with tracking assist, the subject was a fairly static model)
I shot in jpeg mode to fit as many images as i could on the 2gb card they supplied, weren't great at 100% (i know i know don't pixel peep) and because I fidn't know if there was an acr raw plug in that supported the camera yet.
With a grip the camera is nicely ballanced, there weren't any long fast aperture zooms to play with (do they exist?) but I really liked the 45 & 75.
I'm firmly in the EOS system and am not going to change anytime soon, but I did find myself wishing that my m was more like the OM.
Didn't like the viewfinder, large lcd was great.
I was really more curious to see the new lenses, and I was straight with the guys about what I used, and that i'd probably get a panny gh body for my video work.
Impressed overall, I guess the next thing eould be to try an a7 or a7r.
