Set your time machine to "NES."
According to Game Informer Online Nintendo's new Classic NES line may already be available at a store near you. The site's managing editor, and former PGC Head Honcho, Billy Berghammer stumbled upon the new NES styled GBA SP system and Classic NES games while out shopping. The line isn't supposed to be available until next week. After checking around at a few other places they discovered that many stores already had the classics available. It appears Nintendo has shipped them early. So if you're hankerin' for some old school gaming on your GBA try giving your local store a call to see if they have the goods.
