On the fighting combos thing: The Conan game of a few years ago did that, and the system was brilliant, but that was basicly a third person hack n slash where all the abilities Conan gained were related to fighting. I should imagine it would be very hard to implement in a game that also included other career paths.
Being most in favour of a party-based character-driven story with a strong emphasis on personality building as in PS:T, I can't say massive combat options are a priority of mine anyway.
