Despite rumours of cancelation for years now, id Software's John Carmack has confirmed that Doom 4 is in production, that id is focused on blockbuster triple-A titles and that the game will be "done when it's done."
The Bethesda family really is about swinging for the fences. I hope that we do get back to mobile in various ways in the future, but the real aim is blockbuster triple-A titles, and for id that means Doom 4. Essentially everybody will be focused on Doom 4 as a project." - John Carmack, id Software
DOOM 4 was first revealed in 2008, but since then id Software has been mum on the subject. Due to the extended silence around the project, many publications have speculated about the project, with some claiming that the development had been cancelled due to the poor performance of the studio's last title, RAGE.
