While 3DSes continue to fly off the shelves in Japan, Sony's newly-launched PS Vita saw its sales decline dramatically in its second week on shelves.
In all, the company sold just 72,479 units during the crucial Christmas week ending December 25, a historically low number for a console's second week on shelves and a nearly 78 percent drop from the units sold in its debut.
Supply constraints do not appear to be at issue here, as the system's life-to-date sales of around 397,338 units falls well below its initial shipment of 500,000 units.
It should be noted that the Vita is available in two models, a WiFi-only version (¥24,980/$320) and a more expensive model that adds 3G connectivity for a higher price tag (¥29,980/$385) and a monthly connectivity charge. Sony's shipment estimates do not break down the unit's numbers by SKU, nor does Media Create's sales data, so it is unknown if consumer demand for one model versus the other may be contributing to its overall sales.
At 72,479, the system was outsold by not only Nintendo's 3DS, but by the Vita's predecessor, PSP, as well as by Wii and PlayStation 3.
