Sony outlines how you can buy games and DLC once, but play the content on PS3 and Vita.
Sony has revealed that from February 22, 2012, MotorStorm RC, Hustle Kings, Top Darts, WipEout HD and HD Fury DLC for WipEout 2048 and Capcom's Ultimate Marvel vs. Capcom 3 DLC can be purchased on PlayStation Store and will include the feature to play them on both PS3 and Vita for one price.
To clarify the deal with WipEout, US PlayStation blog adds: "WipEout HD and Fury are coming to Vita in the form of DLC for 2048. The full versions of WipEout HD and Fury are not coming to Vita as standalone titles."
If you already own any of these titles for PS3 you'll be able to download this same content to PS Vita for free, and vice versa.
In addition, Motorstorm RC, Hustle Kings Top Darts and WipEout HD and HD Fury DLC for WipEout 2048 all offer Cross Platform Play, which allows users to compete with gamers regardless of which system they are playing on.
Amazon.co.uk currently has the best deal on the PS Vita, offering an 8GB memory card and a WiFi Vita for £210.
