If you watched the Eurosport coverage of Qualifying, Mamola interviewed Jean-Phillipe (M) and specifically asked him about the "secret meeting" that Dorna was having about the spec tire rule.
He went on record saying that he knew nothing about it and the Dorna had called a meeting (presumably with Bridgestone) with a tire company about a spec tire rule for 2008 and that He (and Michelin) were not invited, etc. etc.
What it looks like is Dorna considering a control tire rule with Bridgestone supplying. Decision is forthcoming. It seems to have come as a complete surprise to Michelin that the rule is being seriously considered and that Michelin might be forced out of the championship.
