It's just moments away from Nintendo's E3 2012 event and the first official details of the Wii U, but it looks like detailed specs have already leaked out in a post on VGleaks. If they're true, the Wii U will be very similar to the Xbox 360, with a three-core PowerPC chip, 1.5GB of RAM, and 32MB of EDRAM. That sounds about right, but we're sure to find out more during the event. Stay tuned.
