Sony has shipped around 700,000 PlayStation Vita units to retailers ahead of the system's Japanese launch tomorrow.
That's according to Mainichi Digital (via Andriasang), which says Sony originally planned an initial shipment of 500,000 units, but added another 200,000 units due to pre-order demand.
Many retailers have reportedly said consumers will be able to purchase a Vita on launch day without a pre-order.
It'll be very interesting to see how the system performs in its first week on the market, as 3DS has been the top-selling console in Japan every week since in mid-August price cut.
Vita launches in west on February 22 with at least 12 first-party games.
Before then, UK gamers will be able to go hands-on with Vita at a series of events to be held over the next few months.
