NGBC was released an as far as I know was less popular to XI, so I could see the game being released in a near future.
At least after 2002UM SNKP will not had more games to release in the arcades, and I think that they will need some games to release, at least I'm still waiting for an RBF2, and maybe a Last Blade 2
Hell, I wish that SNKP released games in the game room, I will buy almost all of them
