Chances that they'll play old songs they havn't played for years are actually pretty high now imo, they've been teasing us constantly over the past few weeks, during the countdown live several people said they thought they heard Yoshiki playing Vanishing love on piano (I think) and Toshi was singing a bit of 'I kill you' in this concert, so even if they don't do any old ones tomorrow, chances for them doing them at later concerts are good.
