Square Enix will soon be releasing its Final Fantasy X/X-2 Ultimate Box, which will, obviously, contain both entries in the series. The Ultimate Box will also include the video "Eien no Nagi-setsu," previously only seen in the Final Fantasy X International version. This movie is important in fleshing out the events that transpired in the two years between Final Fantasy X and its sequel. A stateside release has yet to be announced, but the box will hit store shelves in Japan on September 8th for 5,600 yen (about $50 US).
