I happen to be one of the ones who is waiting for fixes/additions. I had several problems with KOTOR (finally fixed in 1.02), and I was not going to make the same mistake with TSL.
I would be real open to a SE, or even an expansion. Of course, since I haven't bought the game yet, I'm not "losing out" like some of you.
With that said, I have, in that past, paid for games multiple times. They have to be freaking awesome games (IMO), or some serious extra content is added. If a game is good enough, like say KOTOR, then I have no problem shelling out a little extra cash for an even better version.
The other advantages with the SE/Expansion idea is that it would give Obsidian the ability to redeem themselves as developers. NWN2 could also do this, but it would not fix the hostilities that abound on account of TSL.
