The specs look pretty impressive - and some genuinely useful extras over the 40D (OK, not a direct competitor but I'm betting a few sales will be dented!).

I see they claim 4 stops for the anti-shake - now that's a tad more useful than a sensor cleaner (something I will always regard as a gimmick!).
A more useful range of exposure compensation (+/- 3.0)
Dual cards - something I really missed after the CF/SM on my Fuji. Excellent! Ensures that you miss nothing through changing cards (assuming you put 2 cards in!)
Now if the ISO6400 and noise control is a good as they claim.........
A much better LCD but no live preview (no great loss!) but no LCD on top (which is a pain!)
