Sony has ‘some answers’ to PSP piracy problem
Admits PSPGo prices were ‘too high’

Sony has concocted an ingenious method of slowing the rate of piracy on PSP, according to Rob Dyer, SCEA Senior Vice President of Publisher Relations: it's just not going to reveal what that method is yet.
Speaking to Industry Gamers, Mr Dyer said that piracy had been "a big problem" for the company over the last few years, insisting that it has "some answers going forward, but we're not ready to talk about that publicly at this point."
In the past, Sony attempted to fight back against pirates through a proprietary hardware standard (the ill-fated UMD): multiple firmware updates that were subsequently hacked one-by-one and the PSPGo download service, which Mr Dyer admitted "confused consumers" and that the "higher price point didn't help".
Going by the methods used to combat pirates and second-hand sellers of SOCOM: US Navy SEALs Fireteam Bravo 3, it wouldn’t be too far a stretch of the imagination that this "solution" somehow involves DLC or online authentication for PSP titles.
We’ll be sure to hear about it later in the year when the flagship title Metal Gear Peace Walker is released, as it would be doubtful Sony will let it succumb to the scurvy dogs without a fight.
