Fallout: New Vegas coming this fall, teaser coming ... right now

Bethesda sent word today that the Obsidian-developed Fallout: New Vegas will start irradiating store shelves this fall. It's a little less nebulous than the previous "sometime in 2010," but it's still not specific enough for our tastes.

No, the real draw today is the second half of Bethesda's release, the debut teaser trailer that we've put just above. No gameplay, but it's got style and Sinatra to spare.

Also ... is that a Helghast? It's not, right?

[Update: Bethesda updated the game's official description with a few details. You can find them after the break.]
"Experience all the sights and sounds of fabulous New Vegas, brought to you by Vault-Tec, America's First Choice in Post Nuclear Simulation. Explore the treacherous wastes of the Great Southwest from the safety and comfort of your very own vault: Meet new people, confront terrifying creatures, and arm yourself with the latest high-tech weaponry as you make a name for yourself on a thrilling new journey across the Mojave wasteland. A word of warning, however - while Vault-Tec engineers have prepared for every contingency,* in Vegas, fortunes can change in an instant. Enjoy your stay.

* Should not be construed as a legally-binding claim."
