Bethesda picked a release date that couldn't possibly be changed. They through out the game 'unfinished' hoping to patch it up later. I understand that a game of this magnitude takes a lot of de-bugging, but I would assume a company would put a little more care into this masterpiece they have made.
Lets face it guys. We are beta testing the game until Christmas.
I don't think that there's a chance in hell Bethesda will allow such a high profile game like this continue to have all these glitches come Christmas time. I wouldn't be surprised at all if we get a fat patch coming up soon here.
