From zircon’s mailing list:
“[FF7 PROJECT RELEASE DATE]
I’ve decided, after intensive research, to set the Final Fantasy 7 ReMix
Project release date as September 7, 2007 – a little later than I had
initially planned, but it seems to more accurately reflect when the game
first came out in North America. We’re wrapping up the last of the
tracks and getting the website together now. Keep your eyes peeled for it!”
