We have no idea if this is real or not, but an Italian video of two people playing something called Wii Qube has appeared, as has some product shots of a "Wii Expander," some "Relax" Wii headphone and a "Wii Silicon Belt".

Watch the video after the break. The shots are here.

There's a press release there mentioning both "Wii Qube" and "Wii Relax".

Nintendo president Satoru Iwata is to keynote GDC today at 9.00am PST (4.00pm GMT). Is a cat out of a bag? That video looks sketchy. We're sure you see the woman's pants at one point.

Thanks, GoNintendo.
