Your Welcome
Thank you very much for sending me this link. It is a rather good arrangement but I was more curious as to whether or not Squareenix plans to release an official collection. Thanks for taking the trouble though
I wasn't sure if I'm aloud to post it, but I don't know if there's an official FFXII Piano collection, but I did find this on Torrents: Final Fantasy XII Piano Collection (download torrent) - TPB
