Yearly numbers for PSP:
2011: 7300k
2010: 9250k
2009: 9850k
2008: 14050k
2007: 12800k
2006: 9500k
2005: 9600k
Bolded the two important numbers to show that PSP had strong launch but then suffered in it's second year. So the future of Vita is not going to be decided by what it does in 2012 where it will make 5-6 milions with ease but in 2013 and 2014.
