I own a PS2 and since recently own a PS3.
I think it's possible for Larian to make a good RPG that's not being dumbed down for console owners.
Concerning the controller issues regarding the complex commands to perform, many games before have made a good use of all the controller buttons, and offered sometimes a real wide variety of possibilities by combining those buttons.
I do think a part of the console community is "immune" to the Larian-type of games (PC style RPG's), but another part of that community (I know it's a bit presomptuous to speak in their name, but what the hell...) really wants nothing more than getting a complex game with a deep background to play in the comfort of their couch.
And don't forget, a lot of console owners are just poor gamers who can't afford a good up-to-date computer. <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" />
