So its clear PS VIta shipped 400k out of 1.4m, so 1m for PSP. But here Sony say this
"Sales decreased 14.5% year-on-year (a 10% decrease on a constant currency basis) to 118.0 billion yen (1,493 million U.S. dollars). This decrease was primarily due to lower sales of hardware and software of the PSP® (PlayStation Portable) and PlayStation®3, partially offset by the contribution of the PlayStation®Vita introduced from December 2011."
Its clear Sony is trying hard to hide horrible sales of Vita and for the first time they have started combined platform which doesnt make sense. So PS3 or PSP didnt ship less.
PSP 1m
PS3 2.1m total shipment 66 million as of 31th June.
