davevh: Heh, you said "polished" about a Polish developer. Try that pun for any other country!
This IS the enhanced edition (delayed for many months); you may wait a while if not forever if you want a perfect game. I played the Witcher 2 enhanced edition 3 times and it still had quite a few bugs and bad performance problems in places (yes, Ubersampling off). No game is perfect, no matter how hard the developers try.
I have put off playing the game since patch 1.06, but it was quite playable up to mid second act (a few hours after entering the mist) where I left off and had immense enjoyment from it. I juggle games around like I do with books, hence the break.
You may want to wait for the Triss patch though to get maximum satisfaction :)
The two expansions are a ways off, and if you play now you can take a break and then build up excitement to play the expansions when they come out.
Flaws and all, this is still one of the few games where full price is fully worth it (and I don't say that lightly!)
I feel like the patches have actually introduced more bugs than I ever encountered on my first playthrough.
