How can you possibly have missed the point of this thread by such a wide margin after being such a large part of the discussion?
Given that Sauber can’t afford to pay his salary and he has basically ended his contract with them, allowing himself the option of driving for another team asap I’d say its pretty certain he’d be at least talking with the teams.
On the plus side, if they don’t get on the pace next year at least there is a huge formula revamp for them to look forward to just down the road
