The pink PS2 is true at least- it was announced during the Game Conference happening in Leipzig, Germany. Seen a picture of it at Gamespot-just doesn't look right to me. That pink unit is just for the European market, btw.
As for the PS3 rumors they both sound somewhat lame if true. Why can't they just show some maturity and accept Immersion's offer to help with the rumble/ motion sensor problem? That other bit about the wand will be a bad idea- by making it an option game developers will be a bit skeptical to make games that support it (as they did with the PS2 hard drive).
