Well, it was the same way with Kotor1. I was sure that the PC version would come later, after all Obsidian will have some extra time to fix things which will undoubtedly be necessary...and Kotor2 will be the only cracker in February.
Hmm, I always focused more on strength as on dexterity. Most important for gameplay (not fighting), though, was intelligence. It should have some special effect on fighting as well.
I would like it that way, too. Handling two blades definitely requires different skills/feats/attributes than a double-blade. I hope the different fighting styles will be improved in Kotor2...
