A new F-Zero game for Wii will be unveiled by Nintendo at E3, currently named as F-Zero Z.
According to German website Nintendo-Planet.de, the new title will feature all the tracks of F-Zero GX and include an online mode.
More cryptically, the site also states that "a weapon system has also been confirmed". We imagine that has more to do with the Babel Fish translation missing something subtle in the language, though.
We're waiting back from Nintendo to deny its very existence, but the rumours would coincide with Reggie's hint that we should expect something big at this year's E3.
