Sources claim that Sony has added an additional 200,000 PS Vita units to be shipped due to massive pre-order demands. Andriasang is reporting claims that the PlayStation Vita's initial shipment may exceed 700,000 units.
Sony had originally planned an initial shipment of 500,000 units, but has recently decided to up the amount by another 200,000 units in preperation for its Japan release on Saturday. The Vita has sold out in advance bookings in Japan, but with many retailers saying you can purchase the handheld on launch day without a pre-order could confirm the sudden 200,000 unit increase.
In addition to the increase in units shipped, Sony has updated their site to include the PlayStation Vita manual. The online User's Guide gives detailed instructions about the basic operations of the PS VIta system and gives hints about how to get the most from your PS Vita. It also gives information on how to expand your enjoyment of the Vita using the PlayStation Network. Check out the full PS VIta manual here.
The PS Vita goes on sale in North America and Europe on February 22nd, 2012.
