Outside of Shinobi, I'm not sure about the other games. They turned SoR and Golden Axe into 3D beat em ups, which seems to imply they didn't have faith in the classic gameplay despite SoR4 doing really well. Crazy Taxi and JSR at least seem to not be changing too much, so I think those may be alright too, but time will tell I guess.
||Secretly hope CT gets an arcade version, cuz that game is a hell of a time on cabinet. ||
