According to EuroGamer, a firmware update for the PlayStation 3 will arrive in the future to allow remote play functionality with the PlayStation Vita throughout the whole PS3 library. The video below, from TGS 2011, shows that feature in action with Killzone 3.
Boy, the Vita’s Remote Play feature sure sounds way more promising than the PSP’s ever did. PSone Classics are great and all, but acquiring trophies through a Wi-Fi connection almost warrants a Vita purchase right there.
