i heard its a license things , but the game is already on PS3 US
why not vita ?
I don't understand, you answered your own question. It's most likely licensing.
Contracts can be written like: [Note - I'm using common English rather than legalise]
"[Sony] is granted the right to have [Game] on the Playstation Network for sale, download, and use on the PSP."
And... then they can't put it up for Vita. They simply don't have the right.
Now, if you wonder why Sony didn't have the contract say "all current and future platforms" it's usually because most publishers are extremely wary about giving away all future rights to something. When they're signing the contract, it's considered smart to leave stuff like that up for future negotiation... unfortunately, by the time it actually is time for renegotiation, it's often an old title and sometimes nobody at the publisher remembers/cares/etc.
Other times, there are timed licenses to force re-negotiation, and again, by the time it is ready to be renegotiated the publisher may not even exist, or may be sold to a bigger company that doesn't care, etc.
Or, even if they want to renegotiate, sometimes the publisher no longer can -- for example, perhaps they couldn't renegotiate their own rights for the soundtrack, so no longer can legally license the game without reworking it.
This could also explain why some titles are available to download onto PS3 and transferable to Vita.
Imagine two possible lines:
A) "Sony is granted the right to have [PS1 Game] on the Playstation Network for sale, download, and use on the PS3."
B) "Sony is granted the right to have [PS1 Game] on the Playstation Network for download to the PS3."
The first clearly states 'use'. The second only states 'download'. It's conceivable [but truly just guesswork] that Sony lets us transfer some titles to the vita because while they're technically not allowed to sell it on the vita, there's no set restriction on where it can be played, so they're actually going above and beyond by letting us transfer.
Licensing is a mess. It would be much easier if they were giving blanket forever licenses to all future platforms, but it's rare anyone will sign that kind of contract since it removes future bargaining power for the publisher.
