I am really looking forward to the Clone Wars line!
The 'FU' line is really not that interesting to me, mainly because I can't play the game without the right system for it. Nonetheless, I will probably be buying all of the FU stuff either because it looks cool or for customs.
The Clone Wars line has potential for new army builders, and vehicles from that era that may have gone unproduced by Hasbro (Homing Spider Droid, AT-TE, etc.) if not for the upcoming show. Not to mention, more obscure Jedi may finally get figures (Roth-del, etc.) and others ma get better sculpts (Barriss, Stass, Aayla).
