Okay!!
This is Avex' first official announcement of Ayu's forthcoming countdown. This is a picture of a ticket pre-sale announcement for TeamAyu memebers.
While last year there was a special "BEST OF" countdown, this one is simply called "ayumi hamasaki COUNTDOWN LIVE 2007-2008 A" again. Although, that's what it's called for now. The kanji in parentheses (仮) means 'temporary name / assumed name'.
Tracklists will probably be out after the first concert (most probably on 12/30) took place.
