I woud NEVER buy firmware! plus, hackers could easily find a way to get the update eboot and then have it flying over the net. Thats the bad thing for sony. Another reason why they wouldnt do it is because they'd still loose TONS of money because they'd allow you to play iso's and iso's are sony's nightmare. They would have to make it EXTREMELY expensive to buy this firmware. Not to mention again that hackers could easily hack into a psp with that firmware and send it out on the net for free. There is just no plus side to this.
