Sony has almost announced Gran Tursismo for the PlayStation Vita by mentioning the title in a customer survey.

The questionnaire was researching customer reactions to the idea of being granted cross-platform access with a single purchase, namely Gran Turismo 5.

"You told us earlier how interested you would be in buying the PS Vita version of the latest Gran Turismo game," the survey (posted online by IGN) reads.

"Knowing that you might be able to get a discount on the PS3 version of the game, how interested are you now in the PS Vita version?"

The survey went on to detail other similar cross-platform deals for PlayStation Plus members.

"Imagine that as part of PlayStation Plus, every time you bought a game on either PS3 or PS Vita, you would be entitled to get the game on the other console absolutely free. So, if you bought Resistance on PS Vita, you could download Resistance on PS3 for free. Or if you got FIFA on PS3, you could download the PS Vita version for free."

Sony has been taking a long, hard look at its PlayStation Plus service, again headed by an earlier customer survey.
