Sony is offering PlayStation Vita owners a free ¥1,000 PlayStation Network ticket. All they have to do is fill out a web survey.
The campaign starts today, March 9, and includes all current Vita owners and, for a limited time, new buyers.
We don't know specifics beyond this. Sony actually hasn't announced the campaign outside of this image that has supposedly been posted at some retailers:
The image uses Sony's recent Vita marketing art and themes. The screen in the image says "If you had ¥1,000, how would you use it?"
Assuming the image is legit, we can probably expect formal announcement of this campaign (along with, hopefully, a URL) during tonight's PlayStation Vita Game Heaven webcast.
