Another surprise reveal from Sony at the Pre TGS press con was the unvieling of the PS Vita TV, a brand new item in the growing Vita family. While the main idea of this tiny device is the ability to play Vita games on a television, the PS Vita TV is capable of a lot more.
Measuring 6cm by 10cm - making this the smallest PlayStation hardware ever, the PS Vita TV has 2 card slots: for Vita games and Vita Memory Cards; it will connect to the DualShock 3 controller with future support for the DualShock 4. While this may already be appealing for those who would enjoy the Vita experience on a bigger screen, the PS Vita extends it's functionality by enabling video streaming services and more. PSone Classics and PSP games from a digital library can also be played; Remote Play with a PS4 is a definite possibility in the future as well.
Note does not come with a controller but does use standard Dualshock 3 controllers, DualShock 4 are supported as of update 3.10, you may need to update to be able to use DS4 controllers
Thanks to Dillo1982 for explaining that it needs a JP account.
Whilst is wont play all Vita games, it does play Killzone Mercenary and Persona 4 Golden. A list can be found here http://en.wikipedia.org/wiki/List_of_PlayStation_Vita_games
