Whoa, now this is a whopper coming (almost) out of nowhere. Nintendo has just slipped out a press release in Japan informing the world that all-new 3D-capable portable hardware is coming, with a full unveiling set for E3 2010 this June. Tentatively titled the 3DS, this glasses-free 3D wonder is pitched as the successor to both the DS and DSi, and will use a "compatible cart" that should ensure backwards compatibility with your vast library of favorites from the older consoles. Nintendo expects to launch the 3DS into retail "during the fiscal year ending March 2011."

Update: Unofficial reports from Japan suggest the 3DS will have a parallax barrier 3D LCD from Sharp, a vibration function, and a "3D control stick." Read about it all here.
