While we are still no closer to a formal release date announcement for the collection, Square Enix have just released a new Tokyo Game Show trailer for Final Fantasy X / X-2 HD Remaster, set to be released as a single collection on the Playstation 3 and individual game collections for the Playstation Vita.
The trailer looks at some of the visual improvements to the characters as well as some of their skills in battle. Surprisingly most of the trailer has focused on the Final Fantasy X side of the collection with only a snippet of Final Fantasy X-2 shown. Given both games should have similar visual quality, this might indicate that they are still working on the port of X-2.
