Basically, those who happen to rock to a Sony PS4 console in their living rooms (or wherever else you decide to place your console, of course) will be able to check out the likes of Binding of Isaac, SteamWorld Dig and Escape Plan. As for those who still remain faithful to the PS3 platform, you will be on the receiving end of Frozen Synapse: Prime and Luftrausers, and PS Vita gamers too, will also be able to access Binding of Isaac, Steamworld Dig, Luftrausers, the Hungry Horde and Escape Plan.
I remains to be seen whether Frozen Synapse Prime happens to fall under Cross-Buy, which would then also make it available on the PS Vita. All in all, one will just need to be patient and wait for an official announcement for Europe and North America in due time.
