Capcom is selling three versions of Street Fighter X Tekken for PlayStation Vita in Japan. You can get a retail copy of the game with a code to add additional characters like Blanka and Lars to the PlayStation 3 version for 4,990 yen ($63). Capcom will also sell a digital bundle with the character pack and a downloadable copy of Street Fighter X Tekken for 4,400 yen ($55).
Let’s say you don’t own a PlayStation 3 or already bought the extra characters, you can get a download only version for 3,400 yen ($43). You’ll still be able to use Sakura and Alisa on the Vita, but without the DLC code you won’t be able to play them on PS3.
