Our pals over at Engadget recently interviewed John Koller, Sony Computer Entertainment America VP of marketing, handhelds and home consoles. Koller revealed that "almost all" PS Vita owners also own a PS3.

"You look at the Vita consumer and a very high percentage - almost all of them - own a PS3," Koller told Engadget. The interview focused on Nintendo's Wii U, which offers functionality similar to the compatibility between PS3 and PS Vita - like using the PS Vita as a tablet controller. Koller said that Sony's not really into offering the functionality stock across all games. It has to be the right content.

"We tell our PlayStation fans all the time that what the Wii U is offering is something that Vita and PS3 can do quite easily," he said. "It's dependent on the content. So we need to make sure the content isn't force fed. And, to us, making sure that the gamer receives the right type of experience is what's most important. So we're gonna pick our spots, but that technology does certainly exist here."
