“You told us earlier how interested you would be in buying the PS Vita version of the latest Gran Turismo game. 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?”There's no reason why GT couldn't be a decent effort on the Vita, but given Digital Polyphony's turnaround times, its not something you'd want to put in a diary. The overall theme of the survey was if you got a PS3 game, would you like the Vita one free? That's an interesting precedent, but really, the Vita needs more unique games to make it a distinct purchase, being a PS3 lite is not a good place for any device.
If you don't know Sony showed off a mock-up box and UMD of Gran Turismo just four years before it actually arrived on the PSP, and while it looks cool (Monaco looks pretty detailed), was limited to just four cars in a race.
