I just saw an article as this same question like a week ago.

A Sony executive recently declared that Marcus Rivers, the smartass 'tween flack for the PSP who debuted at E3 last year, delivered "positive sales effects," for the handheld. Near as I can tell, that's the first anyone's heard of the little twerp in more than four months.
Marcus still anchors the front of Sony's official PSP page. But he hasn't done a commercial for the device in six months.
starcraft: "I and every PS3 fanboy alive are waiting for Versus more than FFXIII.
Me since the games were revealed, the fanboys since E3." 
Skeeuk: "playstation 3 is the ultimate in gaming acceleration"
