Vita: Super Monkey Ball: Banana Splitz.
By the way, Michael, I wouldn't worry about upcoming games yet if I were you. There was a time a while back when I was annoyed because a load of Vita games had been announced but hadn't been entered into the database. As long as they chart in the Japan charts, they'll get entered into the database that week (things like Atelier Meruru for Vita, for example).
By the way, can you add box arts to games and change their names? Because if you do, I have a request.
This is New Little King's Story (not that the name gives you much hint) and it released in Europe. I'll try and find the actual release date if that'd be any help.
