John Carmack decided to say a few words on the upcoming Doom 4 at QuakeCon. Which thus far is just being called “the next Doom”. Couldn't they just give us the name of it already?
He mentions, "The next DOOM game will look like it's built on another engine, as it uses three times the horsepower," according to a 1UP report. Sadly, this will change the fps a bit and drop it down to 30fps. Which to give you an idea, Rage runs at 60 fps.
He also went so far into depth on the game that he mentioned the game would feature "guns, blood, demons, and gibs." I know, he's just full of shocking new information. We do have one request though, please, we beg of you, give us light in Doom 4. We don't like having to get out the flashlight to confirm that there are demon guts on the floor after we've been shooting in its general direction.
