I'm rarely one to defend Pachter, but in 2005 we didn't know the ps3's price and nobody had played any actual Wii titles. The DS was only just beginning to take off, and up until mid-2005 it was seen as a gimmicky alternative to the seemingly more impressive PSP.
Assuming the ps3 would be the next ps2 and the Revolution would be a GameCube that didn't even have a proper controller was fairly typical at the time.
It was an unusually reasonable prediction by the man.
