I think Shia LaBeouf is probably out because of the comments he made on Kingdom of the Crystal Skull, but the franchise doesn't need him. The franchise doesn't even need Harrison Ford and Steven Spielberg for crying out loud. If God damn Frank Marshall wasn't around they could recast Indiana Jones and hand off the reigns to some new director and make the series more like the James Bond franchise, in that the series is constantly being recasted and reinvented every few years at a time.
