I really hope they don't go that route, to be honest. I don't like fighting games, even the "good" ones like Street Fighter or Smash Bros. One of the reasons I felt Dissidia worked so well was that it didn't feel like another genre entirely from the games it was based on. Actually, it felt like a simplified Kingdom Hearts engine, which is a series I REALLY love. In fact, I wouldn't mind if the main numbered games took a few pages out of Dissidia's book and they made a series of retro, nostalgic traditional RPGs for the handhelds like they've been doing with 4 Heroes and Warriors of Light and Darkness.
