I hope they do a Force Career system sort of like the one in Star Wars the Old Republic... we have Jedi Knight and Jedi Consular as basic Careers and then they can branch them further with Shadow and Sage and Sentinel and Guardian, or something like that.
Who says that all future core books have to have a single Career with 3 Specializations? I am guessing they all will, but they really don't have to.
I actually hope not.
This.
I'm really hoping they leave the d20 Jedi fighter/thief/magic-user class system in the past. Even WotC left it behind in SAGA, merely recycling the names for optional talent trees. It was always artificial and evocative of nothing except video games.
