Apparently Sony have started a cashback campaign for Vita (3G only) sales in Japan.
Details are a bit sketchy and unconfirmed (like many Vita details I guess) but reports are starting to pop up on various gaming sites eg
linky.
I've no idea if this will ever materialise in the West. I quite like the idea of a Vita for downloadable material and think the screen is way bigger and better than the 3DS screen, but I'm reluctant to get it as an impulse buy and give it a punt at the current pricing. If a near future price cut is unlikely, a cashback offer might be just as good and enough to sweeten the deal for waverers such as myself.
