Well, it is highly improbable. Given all the publicity and hype it has been given, Bethesda knows that if it completely bombs nobody will probably ever forgive them. They'll basically shoot themselves in the foot with a bazooka.
But alas, if it DOES suck, I will be pissed for having paid 600 SEK for it. Then I'll probably go play Oblivion a bit, before finally finishing Majoras Mask in preparation of LoZ: Skyward Sword. And play some Saints Row 3. And maybe some Batman: Arkham City.
So yeah, I'd probably survive.
