All the teams are agreed on the rules thrashed out with the WSMC, according to Nick Wirth, so Max was probably just up to theatricals on Wednesday and a deal is imminent.
This is an extract from a longer piece by Andrew Benson of BBC Sport.
Fota teams left the FIA meeting on Wednesday after it was made clear to them that they would not be allowed to participate in discussions, however the remaining teams rubber-stamped all the rules that had been proposed and agreed by the F1 Teams' Association.
Manor technical director Nick Wirth, who has a close relationship with Mosley, told BBC Sport: "The five teams left, all agreed it unanimously. I can see, despite hubris, that there is commonality on the technical side.
"There is discussion about a new Concorde Agreement but the fact is the technical regulations are an appendix of the Concorde Agreement - so if you want a new Concorde Agreement, you need to agree technical regulations. It's almost like a chicken and egg (situation) at the moment.
"There is a lot of tension and antagonism but I hope everything will calm down.
"Actually, I am quite confident it will. I'm confident on technical agreement - we will not have two sets of rules - and I hope and believe we will have progress in the next few days."
