Here is what the developer had to say,
“…thanks to the efforts of our friends Mass Media, the Ratchet & Clank Trilogy is available for your PlayStation Vita. Enjoy Ratchet and Clank’s original three PS2 adventures on the go! We hope that fans will enjoy getting to bring these great games with them, and newcomers will enjoy three terrific games on their Vita.
Here at Insomniac, we’re still quite busy with Ratchet & Clank ourselves. We’re developing a re-imagining of the very first Ratchet & Clank game to launch on PS4 next year, which will launch alongside the Ratchet & Clank movie. So stay tuned to our Facebook and Twitter feeds for all the latest there.”
