PSP Software
PSP Software is more difficult to predict based on past history. Annual attach rates are all over the place.
FY End Mar 2005 = 5.7 million SW divided by 2.97 million total PSPs = 1.92 annual attach rate
FY end Mar 2006 = 41.6 million SW divided by 2.97+14.06 PSPs = 2.44 annual attach rate
FY End Mar 2007 = 54.1 million SW divided by 2.97+14.06+8.36 = 2.13 annual attach rate
FY End Mar 2008 = 55.5 million SW divided by 39.28 million total PSPs = annual 1.41 attach rate
With this data, software sales for PSP are not really increasing at all, given the increasing size of the install base.
Therefore to be conservative, I am projecting the same 1.41 software annual attach rate for FY End Mar 2009. With this attach rate, the software unit sales will be 77.91(*) million – which already represents a huge 40% INCREASE in unit software sales compared to the previous FY.
This is already quite optimistic, and may represent a major FACTOR and margin of error with this projection.
Just to compare, if I use a 2.0 annual attach rate, the software unit sales will be 110.5(*) million units – double the previous numbers. This to me, was not completely realistic at all.
Therefore:
PSP Software of 77.91(*) million x $2(*) NET profit = $156(*) million
