That’s what id’s design director Matt Hooper told has told Eurogamer.
“They’re [the Doom 4 team] going in their own direction,” Hooper added. “They’re doing something Doom fans will be happy with. I try to support them as much as possible. It’s a good thing. We’re separated enough to be able to go our own ways, but still connected where we can help facilitate both those directions. It is distinct enough. It would be dangerous… We don’t want to make a re-skinned Doom [with Rage] and then Doom 4 be a re-skinned Rage. That would be bad.”
My speculatometer points to this being an attempt to return to the demonic themes of the original games. Odds on for an unveiling at QuakeCon this summer, and a late-2012 release. But I guess we’ll see…
