Because TGS 2006 isn't big enough for more syrupy PSP and PS3 goodness, Sony demoed the "Remote Play" functions of the two at CETEC JAPAN 2006. And GameWatch and Famitsu were both there to cover it all, and tell all about it. Also, as PSPVault found out, they both came away with radically different ideas of how Remote Play Works.
GameWatch says that Sony says that the PS3 will "throw" (yep, "throw") its video signal to the PSP using Wi-Fi. This means that the PSP can be used to control and see the related PS3 game, making the handheld sort of a Location-free PS3 - minus the six-axis motion-sense, right analog stick, and two shoulder buttons, though.
