I love my PlayStation Vita. While I bring the 3DS with me everywhere I travel, I tend to be playing on Vita most of the time. Unfortunately, major Western studios have given up on the Vita completely. The portable has found a niche as a portable Steam console, with many indies porting their PC games to Vita, but you're not seeing a major Vita game from EA or Ubisoft anytime soon.
Over in Japan though, it's another story. The Vita still sees solid sales in Sony's home region. Japan leans towards portable electronics over home consoles, with the 3DS being the undisputed market leader, but the Vita still being a solid option. That means when Japanese developers are making their games, the Vita is on the table, especially if developers are already making a title for another PlayStation platform. This has seen new Vita games being announced in the past few weeks.
This morning, sim-RPG Summon Night 6: Lost Borders was announced for PlayStation 4 and PlayStation Vita with a spring 2016 release date in Japan. More information on the announcement can be found via Gematsu. Gaijinworks has also said that Summon Night 5 LE is coming to Western shores later this year for PlayStation Portable.
Dead or Alive Xtreme 3 was announced for PlayStation 4 and Vita yesterday. According ot the fine folks at NeoGAF, the PS4 version is entitled "Fortune", while the Vita version is called "Venus". There is no Western release for either version planned at this time, but one couold happen if demand is high enough.
Tecmo Koei also revealed Dynasty Warriors 8: Empires for PlayStation Vita in the latest issue of Famitsu, according to Gematsu. The title is a version of Dynasty Warriors 8: Xtreme Legends which launched for the PS3, PS4, PC, and Xbox One in February.
Sword Art Online: Lost Song was recently given a release date for PlayStation 4 and PlayStation Vita in the United States: November 14, 2015.
Digimon World: Next Order is coming to PlayStation Vita in 2016. Bandai Namco has already shown off the male protagonist Takuto and yesterday they revealed the female protagonist, Shiki, according to Siliconera.
Otome game Amnesia: Memories is supposed to be out in the West from Idea Factory International, but I'll be damned if I can find it anywhere.
Nihon Falcom and Kadokawa Games have announced that Legend of Heroes: Trails in the Sky Second Chapter Evolution will be coming to PlayStation Vita this December. This follows the Japanese Vita release of Legend of Heroes: Trails in the Sky First Chapter Evolution this June. A Western release for both games is unlikely due to licensing issues.
Koei Temco will be releasing an Attack on Titan game developed by Omega Force for PlayStation 4, Playstation 3, and PlayStation Vita. The title is coming in 2016 and a Western release is forthcoming.
Even beyond those recent announcements and reveals, there's still a number of other Japanese titles gracing Sony's beleaguered portable: Dungeon Travelers 2, Resident Evil Revelations 2, Persona 4: Dancing All Night, One Piece: Pirate Warriors 3, Bloodstained: Ritual of the Night, Saga 2015, Valkyrie Drive: Bhikkhuni, Darius Burst: Chronicle Saviours, Atelier Sophie, Airship Q, Tokyo Xanadu, Miracle Girls Festival, and potentially, Zero Escape 3. Even on the Western side, there's recent titles like Helldivers Super-Earth Ultimate Edition, Volume, and The Bridge.
I can't say the Vita is thriving everywhere, but if you're a Vita owner, all is not lost. There's still a number of absolutely amazing games heading your way; they just happen to be Japanese.
