Meh, with all the space battles Bespin Platforms seems kind of pointless, I mean it was a bit too small to actually space fight effectivly. It might have been kind of fun to try it with the improved starfighter controls though. What would really be cool is some kind of combination of the two...
Yavin doesn't make sense to me either, It wasen't a very popular map, but at least where getting Bespin/Rhen Var as well.
As for Lando, I could care less about new heroes actually, they're either just yet another random force user (yawn) or more blaster users who kind of suck. He might have been kind of cool for a Bespin map, but it would be the map itself I really want back, Lando would just be a nice addition.
Not being paranoid doesn't mean someone isn't trying to kill you... or does it?
