Heres my thoughts on what Sony thinks about this.
I dont think Sony are losing as much money as some people may think (if at all), as personally i would never have bought a PSP if all these "Extras" were not availalbe, and im sure many other people are the same..
I would also never have use for a 4GB card, as i'd be unable 'back up' my games.
We're all aware of sites such as, ps**so.. and all the games that are on offer, but of all the games that are downloaded, how many of them would have actully been bought if such a service was unavailalbe?
And all of the PSP's that got bricked in the early days, im sure most of them went out and bought another, bringing more money to Sony.
How much do Sony get per game? Is it not just the developers who are losing out mainlly? If thats the case, then why would Sony even bother to stop their firmware being "hacked", if after all, its in their favour!
Im sure if everything was weighed up, Sony are probably profiting from the PSP Hack Scene.
What are your thoughts?
