According to wii.qj.net Cruisin’ USA has recently been rated by the ESRB for the Virtual console.
Along with that wii.qj.net also mentions a popular skiing game called 1080 Snowboarding.
Could this be the surprise Nintendo is pulling out of the hat? I hope not, I think we all want Smash Bros. To me I think this may be the surprise and Nintendo may release Super Smash Bros the original sometime in March when Brawl maybe gets released. Maybe.
Note: 1080 Snowboarding is already avaliable on the Virtual Console in Japan. Nintendo is coming up on the 200th VC release so lets see what happens.
