>Tekken producer Katsuhiro Harada recently stated in a interview that GGPO is unlikely going to be used for Soul Calibur V's online system due to networking and data reasons.[citation needed] 

 Here is a source  http://www.youtube.com/watch?v=ymYRnT-yFNo&feature;=player_embedded#at=473 

 But actually Harada don't say that he will not use de GGPO. He only say that GGPO is not a magic potion. The problem is that there's too much data (three times more) and they focus on compressing data. But will they use GGPO or not, nobody knows.
