Third-party content will continue to dominate Vita's software library, according to Sony.
While the company has released Vita entries in some of its biggest franchises, from Uncharted: Golden Abyss to Killzone: Mercenary, first-party support is on the decline now that the handheld's graphical capabilities are no longer the main "talking point", according to Sony Worldwide Studios boss Shuhei Yoshida.
He told Polygon: "When we launched the Vita with Uncharted, it was amazing; PS3-like quality in your palm, but as time moved on, you are seeing PS4 quality and people's expectations for the graphic fidelity has gone up.
"It's very fortunate that the indie boom happened and they are providing lots of great content to Vita. Gameplay, game mechanic wise, people want to spend 10 minutes, 15 minutes getting in and out. On Vita, it's great with suspended functionality, so these indie games really great for that from a game design standpoint.
"Instead of watching big stories or cinematics, you can spend hours on Vita. So, I think that's actually the biggest star to help provide great content to Vita going forward. And we continue to make games cross-platform games, especially on digital side."
Asked if Vita will receive fewer first-party games going forward, Yoshida replied: "I would say, yes, that's correct."
Don Mesa, director of product planning and platform software innovation at Sony Computer Entertainment America, recently acknowledged that the company has struggled to get triple-A games on Vita.
"The economics simply don't work with the traditional process," he said. "We have to do something different to get AAA games on Vita.
"We accomplished it to a certain degree by making PS4 games work on Vita via Remote Play. PS Now will be another way, streaming PS3 games on Vita. I can't wait until PS Now is out on Vita."
