I'm just hoping that the combat will be as fast paced and explosive as in the anime/manga. We haven't seen any screens of it yet, but I'll be really disappointed if theres no flying or in-flight combat in this game.
the one thing I see being lame is that well.. ther eisn't a Saiyan race to play as.. so that meens no super Saiyans.. unless you can get like an ability that says your a Saiyan decendant or somehting. Becuase Dragon Ball Z without Super Saiyans would be lame.
I don't think it will be turn based (personally I hope it isn't) and yes I know real time is asking way too much from an MMORPG. The most we can hope for is being able, and often needing, to move around while you attack which really gives a fast paced combat feel (WoW does this really well at some points).
And ya, no Saiyans is kind of a downer. There's still the possibility for some kind of transformation or powered up form though which would be cool.
