Actually, the slim Ps2 got a bunch of colored updates. There was the Black one, the silver one, and the white one that came with the microphone game or whatever.
What happened to consoles with all sorts of colors? Like the N64, there was black, silver, clear purple, clear blue, clear green, etc, and all the controllers came in basically whatever color you wanted, and were all made by Nintendo - not that Pellican crap.
