About FormulaOne: Too much young talent. So when Bottas leaves, Ocon is the most likely option. Verstappen stays where he is as RedBull currently does what he asks them to do. With Mercedes, he will be told what is expected from him. I'm afraid when Hulkenberg has to leave Renault there won't be a new seat for him, or perhaps the seat of Kubica. As said too much young talent to offer an old driver a second chance.
Haas most likely would like to have US drivers, but for many reasons the F1 is not interesting for US drivers. I'm convinced one of the Haas drivers will have to leave at the end of the season, as there has been too much going on between them. Russell might be a nice option for this team, although he has a link with Mercedes.
Gasly desperately needs results. Although I would love to see the return of Daniel Ricciardo to RedBull, I don't think its a realistic option. A swap of Gasly with Albon or Kyat might be an option (depends on where RedBull prefers to sell its product...).
About the MotoGP: Miracles do happen, but I can't imagine Pramac/Ducati will be happy to hire Jorge Lorenzo. Lorenzo was successful with Yamaha, but his first year in 2017 with Ducati was a straight disaster. He kept complaining he couldn't adjust to the bike and finished the year without a single win..... The second year with Ducati went slightly better, but still he ended only 9th in the championship.
Lorenzo is obviously not the champion anymore who will save your day. You don't need to be able to look into the future, to know that hiring Lorenzo will bring you another your of moaning about the bad steering of the bike. And I can't imagine Ducati is aiming for that.
The nationality if the rider has often a lot to do with sales in the country of this rider. I can imagine Spain is an interesting market for Ducati, but you could also put Alex Marquez on a Ducati......
But there is more silly news, I was reading that KTM will abandon their activities in the Moto2, but will remain active in Moto3 and MotoGP.
BTW nice race at Spielberg yesterday......

Great race by Marquez, but a brilliant action by Dovizioso in the last corner! Quartararo showed his talent again. A nice detail, Marco Zeelenberg his team manager, was Lorenzo's team manager when he was still successful......
