Cross Play, Cross Controller and Cross Save show the combination of PlayStation 3 and Vita is as compelling as the Wii U, according to SCEA's John Koller.
"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," the executive told Engadget.
But unlike Nintendo, Koller isn't keen on pushing players to embrace the two-screens life with every game.
"It's dependent on the content. So we need to make sure the content isn't force fed," he said.
"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."
Koller said that retailers ask "all the time" for a PlayStation 3 and Vita hardware bundle, but Sony has no concrete plans because there's a substantial user base already.
"In the meantime, you look at the Vita consumer and a very high percentage - almost all of them - own a PS3. So you see that crossover works," he noted.
Anecdotally, that certainly seems to be true.
