only someone who has access to the Jedi Archives could deleted Kamino from them, so i suppose that Dooku deleted the system and he or Palpatine order the clone army
in my opinion the sith lord will be more than 3, i dont konw why its only an idea, since the game is called "The Sith Lord", but yes, one of the possibilities is that Bastila is the third sith lord, i dont think so, but everything can happen...
is not boring at least not for me, in the other hand the bioware forum is very boring at this stage, with all the secrets of Kotor discovered, theres nothing more to discuss by there
it took me 35 hrs, but without doing all the sidequest the first time. i think kotor was a good game in all aspects, so a longer game will be more fun for a sequel
