Here is what the developer had to say,
Since the HD trilogy was released, one of the biggest requests from many of you was for a version of the Trilogy to come to PlayStation Vita. We’ve heard you loud and clear, and thanks to Sony and Mass Media, the Ratchet & Clank HD Trilogy will be something you can play on the go from 2nd July (and from 9th July in Australia). You can download the whole trilogy for €29.99 via PlayStation Store or pick up a copy at your favorite retailer.
We’re really excited by how well the PS Vita port of the HD Trilogy has turned out. It looks amazing and is a terrific way to play the classic Ratchet & Clank adventures. We can’t wait for you to get your hands on it and take Ratchet with you wherever you may go.
Take a look at the new screenshots below:
Will you be downloading the game come July?
