A re-mastered Doom 3 and Resurrection of Evil combo pack will be released this fall.
Doom is finally heading back to the PC and consoles with a new release, but it's not the sequel you're looking for: it's a re-release of Doom 3. More specifically, Bethesda has announced the upcoming launch of Doom 3 BFG Edition which will feature the original third installment and its Resurrection of Evil expansion pack, both of which have been completely re-mastered.
In addition to the re-mastered games, the upcoming Doom 3 bundle will include seven new single-player levels entitled "The Lost Mission." Little else is known about the added content for the moment, but id Software said that it has addressed one of the biggest complaints about Doom 3: the flashlight. The studio has added an armor-mounted flashlight to the player's suit, allowing them to illuminate dark corners and shoot enemies at the same time.
Unfortunately, it seems that the re-mastered aspect applies only to the console versions. Doom 3 originally appeared on the first Xbox back in 2005, but the re-release now sports enhanced graphics thanks to the processing power of the newer Xbox 360 and PlayStation 3 hardware. Other added features include optimization for 3D displays, 5.1 surround sound, Xbox 360 Achievements, PlayStation 3 trophies, improved rendering and lighting, and a new check point save system. id Software has also fine-tuned the controls.
"Doom 3 was enthusiastically embraced by gamers worldwide at its release,” said John Carmack, Technical Director at id Software. "Today, the full experience has been enhanced and extended to be better than ever, and is delivered across all the platforms with a silky smooth frame rate and highly responsive controls. New support for 3D TVs, monitors, and head mounted displays also allows players to experience the game with more depth than ever before. We think shooter fans everywhere will love it."
As a special bonus, Doom 3 BFG Edition will also include the original Doom and Doom 2 games. The bundle will be released sometime this fall.

I loved Doom 3, and am one of the minority that felt it was better than Half Life 2 - I found HL2 so boring I stopped playing it. You knew full well Doom would be a claustrophobic, linear game and it didn't pretend to be otherwise. But HL2 tried to hide the fact it was linear and fell flat on is arse with a bloated storyline and not enough action. Never understood why it got so many awards.
Console sheep - enjoy the game you should have got 7 years ago :-)
Quake 4 fixed the flashlight already and that wasn't much better.
Yeah there is a PC version too but it appears the "remaster" is for the benefit of the consoles, not the PC as ID doesn't care that much for PC gamers anymore. Console owners are now going to get something approaching the game I played on the PC in 2004, rather than the pale imitation shipped at the time.
