PlayStation Vita supports adhoc with PlayStation Portable
Since the PlayStation Vita is backwards compatible with existing PlayStation Portable games (those available on the PS Store that is), it only makes sense that Sony will allow it to connect communicate with it’s predecessor via adhoc.
While it wasn’t officially announced if the Vita will have the same connectivity with the PS3 using the PSP Engine, it’s technically possible to connect adhoc with a Vita, a PS3 and a PSP (since using said Engine, the PS3 technically emulates the PSP while the Vita does this natively). Of course with this setup, the Vita is at a disadvantage due to it’s disappointing battery life (3-5 hours of game time…. just as long as the PSP Go lol) but if you’re going to play with someone on the PS3 then just make sure you set your play area up near an electrical outlet 🙂
