I don’t really think this has been done before, seeing how Sony’s PlayStation Vita only came into market a couple of months back. In what I deem as a breaking announcement, Phantasy Star Online 2′s PS Vita version will be synced with the regular PC version.
Yes, that means players on the Vita and PC are playing together in the same world/ server. The producer, Sakai Satoshi, is a genius I tell you. Although still an untested area, I am definitely watching this will unfold.
While the Vita version is only due in 2013, which is next year, the game was announced for the PC quite some time back. The game is currently in Alpha phase still for the PC platform in Japan. There is no news at all regarding an English version at this moment. Below are some trailers revealed previously.
