Previously revealed as "Super Mario Stadium Baseball" last October, and now apparently dubbed, Mario Super Sluggers, the Wii sequel to Mario Superstar Baseball has been confirmed for US release, likely later this year. Nintendo briefly demonstrated the game today at a media summit in San Francisco, IGN reports. As expected, the majority of gameplay is controlled by flicks and waggles (think: Wii Sports' baseball with shaky fielding), but some of the demonstrator's motions were "unrecognized by the game," IGN observed. "Not a very good sign."

In addition to the known cast of playable characters, IGN confirms that Sluggers will feature Baby Mario, Baby Luigi, Waluigi, Toad, Toadette, and Boo.
