When Nintendo announced the Ambassador program they promised the release of GBA games by the end of 2011. As you may have noticed, 2011 is coming to a quick end. According to Spain’s Nintendo site (translated by Google) We could be seeing our GBA Ambassador games in 2012.

Available from next year.
Game Boy Advance titles for the Virtual Console service

Yoshi’s Island: Super Mario Advance 3
Mario Kart: Super Circuit
Metroid Fusion
WarioWare, Inc.: Minigame Mania
Mario vs. Donkey Kong
and five titles

I guess we will have to wait and see if this is true. Nintendo is running out of days in 2011.
