If this is truly just an arcade game I think there's no hope of seeing it outside Japan. In Japan you still find arcades fairly commonly (although half of the building are usually those UFO-catcher prize-grab thingies), but in the US they're practically dead.
SE already has an awesome arcade game in Japan: http://kotaku.com/5875066/guns-blazi...anese-arcades/
I've played it many times when there and really wish they would bring it to the US, but can understand why they don't bother.
On the other hand, while Gunslinger Stratos would be hard to bring to console (it has 2 guns which you can combine in various ways to form different weapons, and the guns have thumbsticks and other controls on them ---- very specialized hardware), a fighting game should not be. So hopefully someday they might port this to XB1/PS4.
