Square Enix has released the first official trailer for Final Fantasy X|X-2 HD Remaster.  The HD remastered versions of Final Fantasy X and Final Fantasy X-2 will be making their way to the Playstation 3 and Playstation Vita in the United States and Europe some time this year, and will be bundled together as a set as a Final Fantasy X\X-2 Remaster for the PS3. Unfortunately, the two games will be sold seperately for the Playstation Vita.

Here is a comparison screenshot between the PS2 version and the upcoming HD Remastered version:
