I'm in the same situation as you, but for all games.
same thing happened close to OB's release. no games interests me more than an hour, even games i was deeply into.
it's my pre TES release gaming funk. gonna last till skyrim.
This is pretty much where I am too. I was pretty deep into a couple other games,
but lately, I can't seem to play any of them for any extended period of time. I keep
coming back to the forums to see if there might be some new screenshots/info
video/ANYTHING. I fully expect this to last until 11.11.11. Just the way it works.
