If the Gamecube and Wavebird controlers are effected...
...then why did the supposed 'patent holders' wait until the Wii was a roaring success to sue?
And dispite the number of Wii's sold, I doubt that Nintendo have sold $21m worth of Classic Controlers. (And everyone, even me - being a bit of a Ninty fanboi, knows that the 'Cube didn't sell too well.)
%*^$ing patent squatters!
