I dont think we'll see the full 'meltdown' this time, mainly because I genuinely think 'that Jose' has gone. The Old Jose used to have a ridiculous level of passion that would bubble over and cause a meltdown/fallouts with players, I don't think he has the fire in his belly anymore for all that. My prediction is a relatively uneventful parting of ways in May 2019.
He'll sign a RB, a LB and two CM's this summer. He'll sell Darmian, Blind, Shaw, hopefully Fellaini, a CB and Martial, unfortunately.
We'll finish next season 3rd (Liverpool will be City's main title rival), and reach a domestic cup final. Possibly winning it. We'll go out in the last 16 of the CL after a drab group stage. May 2019, after the cup final, it'll be announced that we've decided to amicably part ways. He'll be thanked for the trophies he won, and for cementing us as a top 3 club again.
Then a new manager will come in and find a squad full of players aged around 28-30+ and will need a big rebuild, so the nonsense will start again.
