Nothing much other than the new gundams themselves. Watching them animated looks better than still pictures xD
Gundam Zabanya and Harute looks too similar to their previous designs in my opinion.
Gundam 00 Qan[T] and Raphael on the other hand looks totally wicked! Qan[T]’s colour scheme reminds me alot of Hi-Nu especially since it looks like he has some funnel/bit system going on whereas Raphael’s head looks alot like GP02
The pilots themselves, well Tieria looks alot calmer now, Lockon/Lyle looks cocky as always, Allelujah looks..like himself and to me Setsuna looks more mature, probably cause of the longer face perhaps? Ah well time will tell, can’t wait to watch it next year! xD
Also loved how they used Decisive Battle as the background music. I love that song! ahhahaha
