One theory I've seen expounded elsewhere (apologies if it's already been posted here and I've missed it) is that it's Hamilton's situation that is the cork in the bottle, not Alonso's or Vettel's. According to this theory, Ron wants Lewis back at Mclaren (while Honda want Alonso) not to mention that Fernando himself would no doubt want the Merc seat should Lewis not re-sign for them, so everyone is waiting for Lewis and Toto to sit down for their contract talks next week.
