What did you expect Dyche or 777 to say?
777 haven't even taken over yet so have no authority to change manager. And even if they do want to change manager in due course, they aren't going to tell Dyche in their first meeting, "sorry mate, we've got bad news - you're getting the sack soon as we're in charge".
And even if they did indicate to Dyche that they would like a new manager, Dyche is hardly going to come out and say yeah I spoke to the possible new owners and I'm getting sacked in 2 months.
Dyche's time as manager here will be dictated by results in the next number of weeks. If he wins games, he gets time. If he keeps losing games and we are cut adrift, then he will be sacked. He's no different than any other manager in top flight football. If relegation becomes the likely outcome, the manager will be sacked.
