According to the ESRB ratings board official website, a "GameKey-Gunsmoke-MegaMan" Plug-and Play device might be on it's way.
"Plug-and-Play" systems have been pretty popular these past few years, an inexpensive alternative to game consoles and the like. Users would simply plug in the device to their TVs and play away. No power cable needed.
The device is slated to be published by Jakks Pacific Inc., a company well known for numerous "PaP" devices. No word on a release date yet.
