Birdo has a prominent role in the Captain Rainbow trailer released recently. In this new Wii game from the makers of Chibi-Robo and GiFTPiA, the eponymous hero visits Mimin Island, home to obscure Nintendo characters. Since not much information is known at this time, it's possible that more Mario characters will be included.

Captain Rainbow currently has no Japanese release date set and has not yet been announced for North America.

NOA sent out a press release concerning some of their 2008 titles, and they helpfully included a release date for the new Wii Wario Land platformer.  Wario Land: Shake It! will be released in the USA on September 29th of this year.

Wario Land™: Shake It!, a classic side-scroller for the Wii console launching Sept. 29, stars Wario, the smelly, bad-mannered alter ego of Mario™. With the Wii Remote™ controller turned sideways like an old-school controller, veterans and newcomers alike can run, jump and smash their way through hectic side-scrolling stages. Players shake the Wii Remote to help Wario take down his enemies, empty bags of treasure or cause earthquakes. Best of all, there are numerous stages each offering multiple missions to keep players coming back again and again to unlock everything, collect more coins or just improve their best times.

The Office of Film and Literature Classification (OFLC) site posted a "G" rating for Super Mario RPG: Legend of the Seven Stars today, just one week after it revealed a new title for Wario Land Shake. Thanks to the Virtual Console, it appears that Australia will get Super Mario RPG for the first time, but no official release date has been announced. Because Australian and European VC titles usually release on the same day, does this mean Super Mario RPG's first ever European release is coming as well?
