id Software have announced that along with Rage (which is coming to PS3/XBOX360/PC) and the free Quake Live they're also working on the next DOOM.
Todd Hollenshead said:Doom is part of the id Software DNA and demands the greatest talent and brightest minds in the industry to bring the next installment of our flagship franchise to Earth.
Kevin Cloud said:You don't even have to worry about how it's going to look on PS3 or 360. Right now we've got it running cross-platform running 60 hertz, and it looks really good," said Cloud. "In terms of what artists are available to achieve--it's something you have to see for yourself. I can say this, but you still won't get it until you see it.
