It's already out. Should TA come out and say "Nope, don't worry, I'm staying" and then later, once things crater, come back out and say "Check that, I'm actually leaving"? I can't even imagine the outrage then. It's out there, hopefully there are conversations underway to iron out whatever the issues are and once it's final, we'll all knowNo, he is allowing it to stay public.
How many hours has it been since this broke and not a word from TA. At a minimum, he is playing Nebraska.
Play the game behind the scenes, knowing full well that what you are doing is likely to become public knowledge. Once it is, get off the fence.
