Fallout: New Vegas teaser trailer

I think I just made some wee wee in my pants.  After the huge success of Fallout 3 it looks like this is shaping up to be a corker of a game.  We understand that its due this Fall (We suspect a October release) and judging by the video it looks as if it is set in a built up copy of Vegas.  No signs of pip-boy just yet but we seriously doubt a Fallout game would be complete without him.  We can only speculate on what this titles offers so watch the video and let us know your thoughts below!
