After weeks of speculation and controversy, Autosport's Toby Moody is reporting that Dorna has withdrawn the proposal to use a control tire in MotoGP. Presumably this means that Carmelo Ezpeleta got what he wanted with the rule, but just what that is, is yet to be seen. Whether that means that Valentino Rossi will be on Bridgestones next year or on Michelins is likely be made clear within the next couple of days. Stay tuned.
~~~ UPDATE ~~~
The proposal has now officially been withdrawn. The FIM has a press release (PDF file) on their website.
