A major feature of the PlayStation 4 is native remote play support on the Vita for PS4 games. During last night's presentation, Gaikai CEO David Perry talked about the work being put in to ensure the fastest response times for remote play. It's a big part of the PS4 and speaking to Engadget, Sony worldwide studios president Shuhei Yoshida said Sony is requests developers for its new console test their game on Vita using remote play before submitting for certification.

Yoshida said the addition of remote play with the PS Vita means developers can create custom control layouts on Vita. "Some PS Vita games make use of the edge of the screen to add contextual buttons - that works really well, I think, and it's easy to see. So that kind of thing I'd like to see developers do on PS Vita over remote play." Of course, the onus is entirely on the developer, but custom controls for the handheld would be swell.
