Epic hasn't confirmed or deny it... so is it real? Should it be added to our front page?

YES!!!! Seriously, how could we know for sure? I guess it's true.

Epic Administrator :

"That video is from last year. It was used to demonstrate the cinematics for UDK."

"Greg Mitchell, the cinematic director for Gears of War 2, did the video. He's not only a super nice guy he is an awesome director."

What they showed at GDC is some jungles that are very reminiscent of the Uncharted series.

Naa, I don't think so.

Check out IGN and their interview with Cliffy B. He has a few hints to some things in his interview. Will Gears of War 3 be announced at this E3? I don't know but I wouldn't be surprised. I think this is the year Microsoft is pulling out all the stops and its seems that the hits keep on coming. If Gears 3 is announced at this E3 then this is by far the biggest year in 360 history, possibly console history. I don't think Gears will be released this year because Reach will be treated as such a huge game not to mention Natal is going to be treated as a new console release. But like I said I wouldn't be surprised for a Gears 3 announcement with a release date of early to mid of next year. Make no mistake though, Gears 3 will be released this console generation. I really believe Sony and Microsoft when they say this is a 10 year gen, these consoles just keep upping the bar year after year in the graphics department. Personally I'm happy about this.

It is real. It's a scene made using a modded UE3.5 ( modded Gears 2 engine ). Done by the director of Gears 2 cutscenes.

Representative of ~Gears 3? I expect Gears 3 to have more colour and look a bit better.
