I guess all those 20k months in the USA has suppressed my expectations of Vita ltd, that and we(well i dont recall) much of anything in terms of numbers coming from EU. So 3 million japan, a lot of bad USA months and a mystery EU number.
Well we're not completely in the dark for PSV numbers.
Sony shipments (of PSP + PSV):
April - June 2012: 1.4 million
July - September 2012: 1.6 million
October - December 2012: 2.7 million
January - March 2013: 1.3 million
April 2013 - June 2013: 0.6 million
July - September 2013: 0.8 million
October - December 2013: 2.0 million
January - March 2014: 0.7 million
Through March 2012: 1.8 million (PSV only)
April 2012 - March 2013: 7.0 million (PSP + PSV)
April 2013 - March 2014: 4.1 million (PSP + PSV)
Maximum threshold for Vita sales: 12.9 million (assuming PSV sold 100% and PSP sold 0%)
PSP Sales in Japan since Vita's release: 1,553,451
Maximum threshold for Vita sales (minus PSP Japan): 11.35 million
For USA + Europe + PAL, let's knock off 3 million of PSP sales for good measure.
Vita shipments: 8.35 million
See? It's not that unbelievable.
