After Many Rumors about Nintendo Wii Release Date, the Only Official Information we have now is from THQ that announced the release date of their games for wii in Europe.
This means Wii in October whether it's that date or not i don't know. I mean it's an official news from a THQ Wii game that IGN says is a lauch title. SourceTHQ communicates that Cars will appear in November 2006 in Europe. After SpongeBob: Creature from the Krossen crab, which should be available in October 2006, is it the second Wii title of THQ.
