Pfft, Valve hates developing for the PS3 anyway. Why anyone would think they would bother with an unseemly and unnecessary peripheral is beyond me.
"Old" Valve hated developing for PS3. Something happened and now Valve is giving Ps3 owners free games and steamworks cross platform gaming. Besides the last link in the article seems to imply that Portal 3 will have move support so maybe Valve doesn't mind bothering with a seeming unnecessary peripheral, but didn't have the time to squeeze it into Portal 2
