If they do, I hope they somehow manage to port the toolkit. NWN as a singleplayer game was alright, but being able to make your own modules and play as a DM is what made it nigh on legendary.
I always got motion sick with Neverwinter Nights and so I could never complete it. The same happened with the very first Jedi Knight (Dark Forces II) game. Even with motion sickness pills I couldn't stand it after awhile. The original Dark Forces was a little better, but still caused motion sickness. I remember similar things with certain N64 games (Duke Nukem comes to mind) whereas other games like Goldeneye there and Jedi Outcast & Academy on the PC/Mac never caused even a HINT of motion sickness, so I have to assume there's some kind of choppy movement or odd frame rate thing happening in those games. Frankly, in some of them (like Jedi Knight and Duke Nuke) I can SEE the choppy frame rate that leads to motion sickness with me.
I've had no issues with Kotor I or II, though or Dragon Age Origins for that matter (by far the best RPG ever made, IMO; it takes things like romance options to the sort of conclusions you want to see but never do in Kotor plus a plethora of ending variations based on character and actions; here you get TWO and nothing you do matters what-so-ever despite their light/dark point assignments until almost the very end. Both options are open regardless of any choice you make which is ridiculous and kills the replay value, IMO. I only had to replay the final two levels to see the other ending).
Now Kotor II had the potential to be awesome, but they never got to properly finish the game (and there was never a direct Mac conversion; you have to play it in BootCamp or virtualized Windows). However, the fans pretty much reconstructed the missing content the best they could (feels odd in some areas, but works for the most part). You can't totally blame the game makers, though. Lucasfilm reportedly REFUSED to let them go back and fix the problems for reasons unknown and unspecified (much to the dismay of the fans) so I doubt you'll ever see it for the iPad.
In any case, once people play Kotor, they're probably going to want to see Kotor II and once restored with the fan update, it's worth playing despite its faults and probably still the better overall game, IMO. If it had been properly finished, it would have been a masterpiece. The final act of the game is still too jumpy/disconnected even with the fixes in place (showing that it was just never fully fleshed out even with the majority of the scenes restored). In short, it's worth booting into Windows to play the sequel.
As an aside...my theory of why they weren't allowed to go back and fix/finish Kotor II is that I think George Lucas HATED Kotor II since it turned his neat little Jedi world of white and black, good and evil upside down on its head and mashed it to pieces, which frankly was what I absolutely LOVED about the game. Both sides are portrayed as EXTREMES and it shows like in modern politics, all BALANCE has been lost completely. And it's this balance that was given lip service in Revenge of the Sith that was a missed opportunity for Lucas, IMO. The Jedi are pretentious overbearing control freaks who won't let any freedom or research into areas they think are evil/dark. Similarly, the Sith are pretty much portrayed as power hungry insane serial killers with a god complex and frankly, that's pretty lame at the other extreme. Most real people fall somewhere in-between these extremes and they're not represented at all by either faction (which oddly reminds me of the real world once again...so maybe Lucas DID get it right, after all if you take the Jedi/Sith to be political and/or religious allegories or satires).
