The internet is rife with storys at the moment, so lets begin, Sony are under pressure from the likes of Nintendo themselves to plug the gaps and stop the Piracy and more worrying for us the Emulation and homebrew scene. The new v2.0 software has plugged every gap that has been exposed by hackers and they have notched up the security even further, so for those on v1.51, v1.52 firmware and if you want to have the hope of running software you must make sure you dont upgrade.
Has Sony finally revealed their killer card, only time will tell but if you have the $$$$ you might be better off sourcing a v1.5 or indeed the fabled v1.0 psp now.
