Hell yes, more ports on Vita. Just what it needed.
I know it needs original content and I agree with you at 200%, but right now original content, no matter how good or fun they are (Tearaway/Soul Sacrifice/Toukiden/Gravity Rush), is not what sells the system unfortunately, at least for most people.
The main reasons are most likely to be able to Play-on-the-go, to use Cross-saves (for some games, ie Dragon's Crown), the evident ports available and requested (Persona 4, Monster Hunter, Type-0, Crisis Core, Dissidia, etc) and the remote-play on the PS4. Those are the main incentives (now) for people to buy it (or to try it).
As much as I want to see more original content (especially as good as Tearaway), we need to show the publishers the value of the Vita. The more we become, the easier it will be to request games.
Games I want to see on the Vita:
Kingdom Hearts 1.5 HD ReMix (with cross-saves)
Kingdom Hearts 2.5 HD ReMix (with cross-saves)
Dragon Quest VIII: Journey of the Cursed King
God Hand
Viewtiful Joe Collection
DMC (original content or spin-off)
Onimusha Collection (1-3 + Dawn of Dreams)
Okami (with cross-saves)
