We really should read things properly. As well as the Banjo details posted on Rare’s site this morning was confirmation that the Viva Piñata is going to release a mystery game before the end of the year.
“The Viva Piñata team is working on a new title that we hope to be able to tell you about soon, and should be in the shops before the end of the year (it’s not Banjo),” said the site.
Your guess is as good as ours. Probably Jet Force Gemini for XBLA, or something.
