I voted yes. I would love remote play. I could never get my PSP to work though outside of my apartment. Seemed it would never connect at a remote wifi spot. It would certainly make buying one more enticing. My PSP died sadly. I had a battery go bad now only half my screen shows video.
Vita will have wireless N Jo, so if your hot spots wireless N you will get a far better range and stronger network cover. PSP was only wireless B what give it a real small range and weak cover.
