If I remember correctly, they did say that the combat system would be built off of KH2, with elements from other games. Command decks are probably out then, but flowmotion is definitely what they mean in being like 3D.
My issue with flowmotion, without actually being able to play the game but seeing gameplay, is that it makes combat too easy for one, and the building scaling is just ridiculous. They seriously need to tone it down a notch. The purple glowing has to go, too.
