It doesn't really matter. As long as "Jedi" and "Sith" are beginning classes and not sort of prestige classes/factions you can join later, then there's going to be a million sith noobs and about half of that jedi and every other class with have around a thousand. In short, it doesn't matter what classes there are, unless something special has to be done, jedi and sith will be the only classes that see play.
