Sadly, I think no one will finish TW3 and Fallout will be too new for it to be a very good discussion. I think everyone will be so high on Fallout since it just came out that it will skew the discussion to just praising Fallout.
That's one of the biggest problems I have with GOTY deliberations and end of the year release games. I don't think you could judge games appropriately when they JUST came out. You need time to let the game breathe and have finish it. Look at something like GTA4, if that came out at the end of the year, everyone would have given it GOTY. But because it came out earlier, everyone cooled on it and saw it for what it truly was and people's judgments weren't hindered because of the newness of the game.
