I think story still has legs:
Lewis Hamilton: Mercedes driver to decide on F1 future after Abu Dhabi inquiry
Obviously some hurt feelings over the last race, and normally you would expect the driver to get over it with the passage of time. But, this could be different. First, it was really an egregious decision made by F1 to hand the victory to Verstappen - it was really the opposite of "settling it on the track". Had both drivers pitted, and gone out on fresh tires, and Verstappen had won, I think most people would have been satisfied that the race was decided on the track, and not in the back rooms. Second, Hamilton does not need F1. He has won everything, he has money, and a knighthood. He will go on and focus on the next chapter in his life. But, I think F1 needs Hamilton - from an image standpoint. If Hamilton walks away - then the conversation about Hamilton will always be on the controversy at Abu Dhabi, and that is bad for the Sport.
I think Verstappen "needs" Hamilton to come back also. I think Verstappen needs to win a championship, over Hamilton, but on the track. Otherwise, he is "the driver who was given a title".
Mercedes would obviously like Hamilton back - he is the face of the team, and gives them the best chance to re-claim the driver's championship. I don't know who they would bring in to pair up with Russell, I assume they have a reserve driver, but it would not be ideal, to start with two new drivers.
On the social media standpoint, Mercedes focused their messaging at the end of 2021 toward saying goodbye to Bottas, and the early part of 2022 to teasing the new car, and Russell. Barely any mentions of Hamilton at all, which I am sure is their way of giving Hamilton some space to figure out his future.
Personally, I hope he comes back. He is still a great driver, and I think a good person also. But, I would understand if he was ready to walk away also.
