Looking great so far!
Awesome news, will have a bit of that me thinks.
I'll be getting this
I loved it when i got it on the original xbox.( I only got a dreamcast about 5 years ago now)
planning to get the original now ive got a Dreamcast 
nothing beats the original! so far I've been mostly disappointed with the shoddy xbla ports of such games as Soul Calibur from the days of Dreamcast, the best one for me was REZ in terms of XBLA ports... I just hope they don't ruin this one as its basically the defining game of the Dreamcast, I mean if you had to pick a game to show people that would tell them all they need to know about DC, it'd be JSR
