To all readers with different "assumptions" of the different divisions:
Just to let you know, the original numbers that were used (*) as assumptions were based on the most plausible numbers - in order to fit some common perceptions about each division.
These are the perceptions that were used to do the assumptions:
1. PS2 software and hardware makes money
2. PSP hardware initially lost money but are now slightly profitable
3. PS3 hardware loses money
4. PS3 software makes money
If you suddenly "tweak" and change some of those numbers, then all the other numbers change, quite dramatically for most numbers that other people comment or spew out.
Let's look at this example:
PS2 software gets $5 profit because PS2 is so profitable.
PS2 hardware gets $20 profit because it's so old and cheap now.
Now you may think that $2 to $5 for PS2 software is not that much different, the same for PS2 hardware profit of $20 from $10.
If we keep everything else the same, this is how the numbers will turn out:
