Famitsu (translated via Andriasang) is reporting that Sony’s new system sold 321,407 units in two days. Those numbers come from Enterbrain, covering December 17 and 18.

The PS Vita – Sony’s new portable gaming system – just came out in Japan (it’ll be out in North America in the new year). That’s just a few more than Nintendo sold for its 3DS during its opening weekend. The big test will be how the Vita holds up over the long term. Nintendo saw sales of the 3DS drop off pretty sharply after a strong opening.
