One of IGN's readers has posted some images from a recent online survey. It mentions Gran Turismo VITA and some new PS Plus features.
...Mr. Latham was asked about Gran Turismo on PlayStation Vita. "You told us earlier how interested you would be in buying the PS Vita version of the latest Gran Turismo game," the survey 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?"
