This franchise needs to be able to survive without any one individual person. Otherwise it's future is very limited/already over.
Unfortunately, I think this is what has already happened.

Maybe if things were done differently from the beginning, it could've been different, but I know that FOX is pretty much thinking an X4 isn't possible w/o Hugh or Halle...and Jean/Scott are 'dead' as far as we know...it's all screwed up

They put the most mainstream, popular X-Men in the first film, and where do you go after they're gone? This is the problem I think they're facing. Also remember that 'The Last Stand' was a title FOX gave this film. The script was written before that title was created, and it's obvious this script wasn't really supposed to be 'the last stand'.
Honestly after X1, X2, X3, and Wolverine I doubt Hugh will return to the role again unless it's for Wolverine 2, etc? He's played this character for a long while now, and career wise he'll likely move on after the Wolverine film(s).
I do see the young team spin-off happening though. With Storm (maybe) running the school...Halle has expressed interest in returning, so that seems possible. Still, it won't be an X4...imo
Maybe after the spin-off films, they should reboot the franchise in the far off future?
