KTM won't demote Binder unless he has a total stinker of a season, which is unlikely. KTM will try to get Marc I'm sure (if only for the Red Bull connection). The problem is what happens to that second KTM seat, does Marc get it, or Acosta? would any of them be OK with being in a satellite with a lower salary? Acosta could accept but there's also that stipulation in his contract that makes him a free agent if he doesn't get promoted to the factory KTM seat. KTM could re-negotiate a new deal with Pedro to keep him at GasGas with better conditions. But if Marc doesn't go there, it's one less headache for the Austrian manufacturer.
For Marc to get a full factory setup at Gresini, he needs to bring some sponsors to foot the bill. If he commits for another two years, sponsors will come, but he will have to ride for a low salary regardless. I don't think he'll end up in Pramac because Ducati would feel nervous about somebody outside the factory winning the championship, which is the same reason I don't think he'll get full factory support if he remains in Gresini. He'll be aiming for return to a factory seat, anything that isn't Yamaha but I don't see a return to Honda yet, I believe they won't be ready to fight for top spots so soon, but it's the fallback option for Marc if everything else fails.
I think Enea will be out unless he fights for the championship until the end. People are sure he'll regain his 2022 level but I have yet to see, he's very good riding around Sepang and Losail so I reserve my judgement until I see him in other tracks. He's either Aprilia bound or rebounds to Gresini/Pramac.
As for Jorge, I think his relationship with Ducati has soured a bit and viceversa, he feels slighted about not getting a factory seat and he's made his complains known, Ducati probably wants someone who gives fewer headaches in team dynamics as well. I believe he has his mind set on leaving already.
Quartararo either remains in Yamaha, signs for Aprilia or does a Marc and goes to a satellite Duc. Pramac would be good for him.
