Is seems there is some people who did not understood that KotOR II flaws were just caused by LA. They wanted the game for Christmas (and only for US Xbox owners...) while Obsidian initially planned to release it for "Winter 2005", eg March. I'm quite sure that if Obsidian had a few months more to finish it, KotOR II would have been far far better than the first game.
Unfortunately, it won't be the case unless a content patch fixing the incoherent ending is officially releseased.
You don't (neither do I) know Atari's policy about the release of NWN2, so don't anticipate nor say it will be a bad game. Most of Obsidian's staff are coming from Black Isle Studio who developped the 2 Fallout, the excellent Planescape Torment and the 2 Icewind Dale, plus some addons for ADD games. So I really think there are good developpers and very able to make excellent games.
