id announces id Tech 5!!!

Just like years ago, when id showed their Doom 3 engine at a Mac conference, this year's Apple WWDC (world wide developer conference) was no different!
John Carmack was on stage announcing their top-secret new engine, called id Tech 5, complete with a video and all! The engine will be used for a new IP, which they're keeping secret until the Mini-e3 next month.
Here's the story from Joystiq, go there for the fuzzy pictures:

Carmack introduced the technology, saying, "So the last couple of years at id we've been working in secrecy on next-gen tech and a game for it ... this is the first time we're showing anything we've done on it publicly." He describes the demo happening on screen: "What we've got here is the entire world with unique textures, 20GB of textures covering this track. They can go in and look at the world and, say, change the color of the mountaintop, or carve their name into the rock. They can change as much as they want on surfaces with no impact on the game."

Carmack finished off the tease saying, "We're going to be showing on a Mac, PC, PS3, and Xbox at E3, we'll have another Mac announcement at E3."
