I know "source" is a worthless word these days, but I have the "impression" we won't know anything before Wednesday. That being said, I suppose it's possible things could leak sooner than that. But I wouldn't expect the press conference/pep-rally-welcome-coach ******** until Wednesday or later. Maybe Tuesday.
To clarify, I personally have no idea who it will be. But I do know someone who does have an idea and is very, very close to everything going on... but he's only able to spare when it might be, not who it might be. Sorry if this causes any vagueness or confusion, but that's all I have to work with. It's almost like Byrne has a gag order on this ****. But I have faith he'll make a good decision. That being said, I'm tired of waiting.
