At the risk of stating the obvious, developing a game for multiple platforms and adding online play aren't free. If SC3's budget was spent on those things, it would probably result in a game with fewer characters and less single-player content. Kind of like SC4, really.
Also people forget how shit and limited online gaming was back then. What people found acceptable for a shooter was not acceptable for a competitive fighter. Today we have complaints about 8 frames of delay which is nothing compared to the online garbage Tekken 6 was. Excellent online play was a super luxury and this isn't even considering the online player base being way bigger now than it was back then.
