Sony announced a new deal recently at Gamescom: for select first party games, customers who purchase the PS3 version will also receive PlayStation Vita digital copies for free. This initiative will include PlayStation All-Stars, Ratchet & Clank Q-Force, and Sly Cooper: Thieves in Time. These also include the ability to cloud save so you can play the same saves across platforms.
According to Forbes, EA is considering it, but has no announced plans.
This is a pretty good deal for anyone who owns both systems. It's friendly to both consumers and beneficial to Sony. Cross buy will encourage the sale of PlayStation Vitas which has not been selling well globally. The deal will also encourage the sale of PlayStation Vita memory cards which are proprietary. Consumers will be able to take full advantage of their hardware and not have to buy a game twice or replay if they decide to own on both systems. It's also relatively light on the budget, especially in a year where console sales are down.
The downside for consumers is that the Vita will most likely always have to be connected to the internet in order to properly cloud save, but that hasn't been announced yet.
All in all: It's an interesting announcement, and we'll see how it plays out this holiday season.
