Epic Games has confirmed that there are currently no plans to release a demo for Gears of War 2 in the lead-up to its November launch.
"[There are] no plans for a demo," associate producer Tanya Jessen told Shacknews. "The reason being that it's been such a fast turnaround. A two year production cycle, for a game of this caliber, is really short.
"Our focus is always on putting out the best possible game we can. Whenever you do a demo, you have to basically ship a whole separate product. As far as our plans after we ship, I can't really speak to that."
So there you are, then. Definitely no demo until after the game is released. Don't expect one after launch either, Epic knows you're all going to be buy it anyway.
