Apparently a poster on GAF is not normal. They were actually reading the official rules of a Playstation contest and in the rules it states the retail value of the Vita is $180. Of course the current price of a Vita is $200, so we have the possibility that its either a typo ($179 is pretty close to $199) or its set to match an upcoming Vita price drop at E3.
