It's a sad truth, I suppose. Perhaps in another 5 years or so we may see a KotOR 3, or maybe in a decade. I just hope they do add some more class stories for any expansions they announce. I'm sure a lot of the KotOR crowd will come back for any expansion packs. It'll be like the old RPG expansion packs, like Awakenings or Throne of Baal.
I'm optomistic in that I think that tablets will be the sort of gaming device where RPGs will be more at home. And there is predicted to be quite a lot of these sold.
As for the old Republic as imagined by BW. Well this is the last we will here from them (this game) I should think. So let's enjoy what we have. Whilst imagining what KOTOR 3 could've been, of course!
