Did you ever think to yourself, "Hey, Final Fantasy X and X-2 are good and all, but what they really need is another 30-minute cut-scene during the credits?" You're in luck!
According to the Japanese publication Shounen Jump (as translated by Siliconera), the upcoming HD remakes of FFX and FFX-2 (to be released on PS3 and Vita this fall) will come with a 30-minute cut-scene that plays over the compilation's credits -- presumably at the end of FFX-2.
I reached out to Square Enix earlier today for confirmation/further details, and I'll update if I hear back from them. Hopefully they don't go all Harry Potter on us: if this scene is set in the distant future and Tidus and Yuna have a kid named Jecht Auron I'm gonna break my TV.
