Remote Play Diablo III on Sony's Playstation Vita!

This alone may be the reason for a Sony Playstation Vita. Now how about Final Fantasy XIV? That'll seal the deal! Once again, Sony is setting the Vita to be the ultimate Playstation 4 accessory. https://twitter.com/Diablo/status/400073137590530048

Now, which version Vita should I buy? Generation 1 with the OLED or Gen 2 that's slimmer, standard charger, lighter but powered w/ an LCD screen.
