Pretty funny that just after we edit the thread title with Vita's last stand, more games get announced for it. Thanks for the edit MUGEN :)
Anyway, Bullet Girls Phantasia announced for PS4/Vita:

Previous games were 60fps on the handheld, hope this one is too. Sounds kinda neat, Bullet Girls gameplay in fantasy setting.
