A surprising find came up on the net today, as a trailer for the Kanon anime (the 2006 version) was found up on ADV's website. Now ADV Films has yet to announce that they've licensed any of Kanon yet, although they've
hinted at it before if its sister series
AIR sells well enough. But despite that, this seems to make it all but completely official. Still, the American anime fandub awaits for the word to come straight out of ADV's mouth.
