I really wish they would make a 2D sprite-based sequel to Jump Ultimate Stars for 3DS instead. That would be way better in my opinion and could easily fit upwards of 100 characters.
But then we wouldn't be able to play it because of Nintendo and their stupid region locking. The nice thing about Sony systems is that we can import the game (because it obviously won't be getting a Western release)
Anyways, I'm super excited about this! JUS was one of my favorite fighting games of all time, so I would absolutely love to see a sequel, even if it's not quite the same type of game. From the sound of things, fans will even be able to vote on which characters they want to see in the game. I'm definitely interested.
I think the reason some I'd the people are so split about this game is because one side wished it was a sequel to jump ultimate stars, hey at least ganbarion is planning to make a new game soon because their looking for people
