Where should we be looking for it? Gamasutra got some new details about lonesome road. the Fallout wikia is constantly active, and i usually find things out through google news. so do i check obsessively here or google news or where ?

On steam go to Fallout New Vegas game page and the newest achievements on it are for LR.

I'd check here every few days as soon as we get a date you'll see a million threads about it and its likely the forums will be the first to know.
