Nintendo surprised everyone today with the revelation that it has created a special adapter that lets players use GameCube controllers (considered by many to be the only way to real way to definitely play Super Smash Bros. Melee and Brawl) on the Wii U.  This snappy little box connects to the Wii U via USB and was revealed as part of the company's video hyping its Smash Bros. tournament at E3.  Curiously, there are no announced plans to sell this peripheral to the general public, but I can't believe the company would show off this gizmo and not sell it.  Perhaps they're waiting for fans to loudly demand and petition for its inevitable sale which allows Nintendo to say that they caved in to gamer demand.  I can already picture a special Smash bundle that includes the game, this accessory, and that snappy GameCube controller with the Smash logo on it.  My hope is that this add-on is just the start of uses for the GameCube controller; perhaps a wave of classic GameCube games is coming to the Wii U's Virtual Console service.  A man can dream...
