In my eyes, that's the natural step to do with Vita.
We know for a fact that the system wasn't commercially successful and that they won't be developing many more 1st party games, except for the casual japanese game port. Will these games, that share multiplatform release, be successful and make the Vita a must have? No. But it can surely please those who still have one.
Sony isn't after the masses anymore but they will try and please, the ones who still play on their Vita, the way they still can.
