I found no information about using a Playstation 3 DS3 or even a PS4 controller on the Vita as an input method. I just found out, that you can stream the Vita screen over PC/network to a different screen. (Thanks to this Thread http://gbatemp.net/threads/any-way-to-stream-games-from-ps-vita-to-pc-or-mac.449854/ ). I was thinking about getting a PSTV to play Vita games for that, but maybe there will be a option in the future to have a Vita for that way? I read DS3 needs USB sync (like on PS3) BUT the Vita has a USB cable and in theory you can connect a DS3 to it via USB female to mini USB male Adapter... Maybe even regular Bluetooth is possible. Anyone has an idea?
