We still don't know when Nintendo 3DS' eShop download service will be available—though May seems like a good guess—but Nintendo's already started making with the sweet enticing come-ons. Not like we needed them. Still, when eShop launches, Excitebike 3D Classic will be available OMG FREE (for a limited time) to showcase Nintendo's new line of "3D Classics." Same retro look, new 3D effects. No telling what other games will get the 3D Classics treatment, but you know we're waiting for Battletoads. [via Joystiq]
