Rumor has it, an announcement by Indianapolis or Brno. I, think Brno is the cut off. Most current rider's usually have it in their contracts that they make decisions no later than a certain date in August. Least that's what was the deal with Crutchlow, and them saying he had til Brno to figure it out. You are right, Lorenzo is sure dragging his feet with this one.
Marquez was the surprise in that we all knew he would re-up but he did it so fast. Rossi, Pedro, Dovi and Crutchlow all were timed about normal in correlation with the past. Usually you don't see rider's this late in the game announcing anything unless it's a team signing brand new riders(i.e. Aprilia and Suzuki).
