LucasArts is never going to invest time and money into revamping a ten year old game. Believe me when I say that I'd be the first in line to buy it though. Would they ever possibly remake it entirely? Parhaps but I wouldn't count on it.
Seems like they have a habit of that, either not making things for certain platforms or if they do not finishing or fixing the game and then once its done just moving on to the next thing instead of spending time trying to make their previous game better. This was probably something that should have been done years ago when the game was still relatively new.
