I don't think so. The speech pattern didn't match Byakuya. Sure, he addressed Ichigo by his full name but Byakuya would NEVER say, "Would you wake up already?" No way. Probability says Byakuya but I say someone else, although there's no one else who matches that discription. Maybe Aizen. Nah, why would Aizen wake him up, of all people? Until then, it's Byakuya.
