Tonight, Sony and Square Enix showed images of Final Fantasy X, the HD version for the PS Vita. Here are the HD character models for FFX's Tidus and Yuna. Note that they were taken from a standard definition stream and are not in HD.

The HD version of Final Fantasy X was first announced way back at the 2011 Tokyo Game Show for the PS3 and the Vita. Last summer, Final Fantasy XIII director Motomu Toriyama indicated that the game was a while off saying, "Regarding HD conversions, there is a lot to look into, so please wait a bit more."
Game producer Shinji Hashimoto from Square Enix apologized for the long wait, adding that they were concentrating on developing the HD version properly for the Vita and the PS3, aiming to do the best HD version possible. No release date was given tonight, but Hashimoto said the game's release date announcement would be coming shortly and told everyone to "wait for that."
