Sega is apparently ready to release a simple console that you simply plug into your TV to play some built-in classic games. This is similar to the offerings that Atari and Namco have released in the past year or so. Currently this is only in Japan, but we might possibly see it elsewhere. As for games, looks like there's a Sonic in there, Golden Axe, maybe a Puyo Puyo game (some puzzle game anyway) and a few others too...
