Considering there's actual data to support piracy of the PSP with Dissidia being pirated five million times, Phantasy Star Portable 2 being pirated over four million times at that time, gives me more on the opinion that people pirated more games than your "can or could," theory.
The PSP is a portable device that is in no way close to the graphical capabilities of the PS3. Anti Vita consumerists use the Vita being a portable PS3 as why the system doesn't sell, so you're now going to say this is the reason the PSP didn't sell? How is it that it's sold for such a long period of time before hand? Don't you think sales of the PSP would have stopped after Uncharted which was released in 2007 rather than wait until God of War 3? Your theory on why the PSP sales slowed down is full of holes.
While your post is an unproven theory, my posts is backed with factual information that shows numbers of how many downloads of specific games in that period of time. Downloads that exceed the title in question multiple times over. Time frames that correlate decrease in sales to when all PSPs aside from the Go were opened up and allowed piracy.
