Final Fantasy X/X-2 HD Remaster will hit PlayStation 3 on March 18, 2014. That still very barely qualifies it for its previously announced winter release window. Square announced the date today, along with a Limited Edition for the set of two games.
As previously reported, the remastered games will include Eternal Calm (FFX) and Last Mission (FFX-2) that were previously only in the International versions. FFX-2 will also get a extended ending with some new voice-over work.
This is only the PS3 version, mind, and Square Enix says that the date for the Vita version will be announced sometime later.
