Championship Edition and Pac-Man Battle Royale. This marks the first time you'll be able to play the multiplayer Pac-Man game without visiting your local arcade (apart from an iPad demo, anyway).
Pac-Man Museum is coming to XBLA, PSN, PC and the 3DS and Wii U eShop. The press release also notes that, for whatever reason, Museum will not include Championship Edition on XBLA or PSN.
In other Pac-news, Pac-Man: Championship Edition DX is getting a free update that adds new content, including improved leaderboards, achievements and medals. It also features "access to additional DLC mazes, music and graphics." These include the ability to play with graphics from other Namco games, including Dig Dug and Rally-X. The update, which officially turns DX into DX+, is headed to Xbox 360, PS3, Steam and Windows 8 this summer.
