Sony really should have learnt by now: hinting at things in surveys is a bad way of hiding potential upcoming developments in the PlayStation world. We already found out about the evolution of PlayStation Plus way before it's official unveil and a handful of HD Collections were tested out via survey last year. In short: Sony are judging interest in a set of products yet again and, boy, are you going to be interested.
Sent into IGN by one of their readers, pictures from the survey show that Sony are at least considering a Vita version of Gran Turismo. That shouldn't really be a surprise to anybody, Gran Turismo has found its way onto every PlayStation product released worldwide and a new member of the Turismo family on the Vita would make perfect sense. The interesting thing is that the survey asks whether you'd be more interested in the Vita version if, on purchase, you could be the recipient of a discount on the PS3 version.
Further questions ask about the possibility of, as a PlayStation Plus feature, giving both the PS3 and Vita versions of a game for a single price.
I should just note that this whole thing is about measuring interest for certain features and so you probably shouldn't expect any of these plans to be implemented any time soon; still it's nice to know that Sony are willing to meet their users half-way when it comes to buying titles on both the Vita and the PS3, so it'll be great to see what comes out of this survey.
