According to what looks like a Jump Magazine leak (below), the HD remaster of Final Fantasy X is coming to the PlayStation with a Final Fantasy X-2 remaster on the same disc.
Both the Final Fantasy X and X-2 HD versions are also supposedly packed with the "international version" content. Originally, that consisted of bonus extras like concept art, trailers, and interviews.
The HD versions of Final Fantasy X and its sequel X-2 will be sold separately on the Vita, the rumored leak states.
In September 2011, Square Enix announced that Final Fantasy X was headed to the Vita and the PS3 in HD. Last month, Square Enix showed off the HD version of Final Fantasy X for the Vita.
Kotaku is following up with Square Enix and will update this post should the company comment.
