Introversion

i know this is not likely to happen, but is it possible IV might expand its D+ sales to the PS3 if d+ does well on the xbox 360?

Possible, certainly. Unless there's some exclusivity contract between MS and IV. Don't hold your breath.

I guess thats something a IV "executive" could tell us. I hope IV didnt let the MS guys do that to them. But hey any business is good business.

I'd presume not, or certainly not for a long while.
Given the length of time a 360 release has taken and the similarity of the 360 and PC architectures, porting D+ to the vastly different SPU would probably take about 4 years.

My guess is most likely no, because if you look in the data archive of the game folder, there's thumbnails of 360 buttons, and keyboard/mouse buttons, but I don't see anything indicating work for another console.
