Gamestop.com has 5 listed Revolution games available for prerelease on March 1, 2006. Though their disclaimer says “content is based on the best available information on price, and release date” this is 
coming from a legitimate game source. They are using the term “pre-release” which in no way implies an actual release. But it couldn’t be too far off.
This does happen often in retail solely as a means to build hype and sell more product for the retailer. Still, it’s promising, so maybe an early summer release still is a possibility. Must…get…date…from…Nintendo.
