The PS Vita continues to see declining sales numbers after a great start (321,000 unit sold shortly after its mid-December debut). In the second week, the Vita sold 72,000 units and now in the third week (Dec 26-Jan 1) it only sold 42,000 trailing the PSP at 62,000 and 3DS at 197,000. In addition the recently released software top 20 sales numbers didn't even contain one PS Vita title.
