Apparently Ainge was on 1510 and was asked: "Will Marion be here next week"
First he said "no," then he said he didn't like to comment on things like that. (edit: he apparently laughed off this question too - so take that for what its worth)
They are taking a wait-and-see approach to Gary. He also mentioned something about the roster being pretty much set, but I'll believe that when I see the ball tossed up for the first game.
Update: Apparently Ainge was on FSNE and said that he called Banks twice, including on Wednesday to warn him that the trade might be revised. Banks asked why he gave up on him, and Danny responded that he didn't give up on him, but that he was traded for a future Hall of Famer.
Sorry that this is coming third-word-of-mouth, but I don't have access to a TV or radio and I'm relying on other people's reports.
