The Xbox version of DOOM 3 might not see release this year, id Software's Todd Hollenshead tells CNN Money. Though publisher Activision has said it's penciled in the Xbox version for this December, id has the final say as far as when the game ships, and the Xbox version is evidently still deep in development.

"It's still up in the air," explained Hollenshead. "DOOM 3 is a game that on the PC is very finely tuned. There was a lot of play balancing. The stuff that was supposed to be tense resulted in a lot of tension for players. The stuff that was supposed to be scary makes people crap their pants. We want the Xbox version to be just as good."

As for the future beyond DOOM, Hollenshead said id plans to turn to an original property for its next project -- check out the interview for other details.

Well like they say,it'll be done when it's done. i rather have them take there time and get this right. and not make it a rush job and just make it out for the holidays. but if they can get it done in time im all for it if not then they outta push it into next year. and besides doom 3 might get lost in the mixed if it's released so close to halo 2 released date.
