Finally we get the word on the release date for Banjo Tooie on the Xbox Live Marketplace. The bear and birds second adventure will be out next week on Wednesday the 29th for probably the same amount as the original Banjo Kazooie, 1200 Microsoft Points ($15)
The game will allow you to swop any of the hidden eggs you found in Banjo Kazooie at Heggy's Hen for brand new moves that were not on the original N64 version. Here's a little video that came out a couple days before Easter that shows you a preview of the stop n swop and where to find any of the eggs in case you missed them.
Also a list of all the achievements can be read here if you're interested.
