Hey!
I have played skyrim a lot, i have never had some problems with my game, had 2 problems with loading the game and the game freeze. This is only the problems i had have.
Should i update to 1.2 or just wait to 1.3 next week?.
I have ignored to update to 1.2 when i start the game and never installed the game to the HDD. I have done this to prevent to get the problems some other players have.
Should i update or wait?

Honestly this is really up to you. I have updated and haven't experienced any of the problems others have had. I did have the texture issue with both previous versions but 1.2 seems to have somewhat fixed that.

I wouldn't worry about it too much though. I'm sure Bethesda is working on the issues now as I type this and we should see another update very soon.
