Doom 4 TBA

Doom 4 (DOOM Is the official title) is the upcoming installment of the Doom series by id Software and a sequel of Doom 3. It will use the company's new id Tech 5 engine. It was announced as in production on May 7, 2008,[2] following speculation by John Carmack at QuakeCon on August 3, 2007.[3] As with previous Doom games, Doom 4 will primarily be a showcase for the computers, with John Carmack stating that the computer version of Doom 4 will look significantly better than the console versions due to the power of high-end computer hardware.[4]

Arent they busy working on Rage? Was looking forward to that one..

Old news much? Like Doom3, it will be written in OpenGL.

They are, simply because D3D is easier to code for. But ID's used OGL for a while now (Doom 3, which broke a lot of ATI cards due to poor OGL support), so theres no real surprise there. A lot of smaller studios (Stardok) also use OGL.

OGL is just as capable as D3D (Doom 3 still holds up pretty well, not bad for 2001...), its just a harder language.
