Some bonus DLC will come with Final Fantasy X/X-2 HD Remaster for use with Lightning Returns: Final Fantasy XIII.
If you buy the PS3 copy of Final Fantasy X/X-2 HD Remaster, you’ll receive a Yuna costume complete with staff and victory pose for Lightning to use in her own game. Square Enix emphasized that the DLC only comes with “first-run” versions of Final Fantasy X/X-2 HD Remaster only. Bear in mind the DLC is not included in the PS Vita version.
Lightning Returns: Final Fantasy XIII comes out from February 11th while Final Fantasy X/X-2 HD Remaster is out in March.
