The latest issue of Japanese magazine "Jump" has confirmed that the Final Fantasy X HD PS3 version will come bundled with Final Fantasy X-2 HD as well. On Vita, the two titles will be sold separately.
This is the first tiem we've heard any word of X-2 getting the HD treatment as well. The game wasn't a spectacular sequel, but it's nice that Square Enix is going to throw it on the disc.
Thanks, Nova Crystallis
