I dunno... there's reasons to hope and not to hope. On the one hand, not even Lucas Arts is in the business of ticking off its customers. Pulling out the sketchy business school knowledge: fixing up the game would be adding to the 'augmented product' raising the value of the game and improving the reputation of both companies (and thus future sales). If there's enough of a response, it could actually be worth it to both companies to sick a team on the game for a week or two.
On the other hand, a lot of people probably have a lower expectations of the ending. Somewhere along the lines of 'oooo... shiny.' They won't care if Atton gets his arm hacked off or not, and lets be fair; a good part of those 80,000 views are us checking back to see if there's any news. Plus there's the whole Xbox-can't-update thing. I guess we'll see.
Still, though, both companies would get a lot of milage in my books by paying attention to their fans on this one.
