Konami's pachinko company, KPE, has filed a trademark for "Big Boss."
As for what the trademark entails, it most likely means that a "Metal Gear" pachinko game could be in the works. That, or a different game, though most likely something small scale after Konami's decision to push for mobile and pachinko market being the primary focus.
