Sony recently announced that some of the content digitally purchased via PSN will be available on both PS3 and PS Vita for a single price.
Titles such as Motorstorm RC, Top Darts and Hustle Kings can be shared across both platforms, while DLC for Wipeout 2048 and Ultimate Marvel vs. Capcom 3 can be used on both systems with a single purchase. Wipeout Fury DLC will be compatible with Wipeout 2048 when it releases later in spring.
The content can be purchased on either system and be used on the other platform free of cost. If you have already purchased them on PS3, you’ll be able to download them to PS Vita without any charge.
