The lastest chatter is, MM and his team is caught in some ECU conspiracy. We will have to see how that pans out.
No doubt in my mind he is going to be one of the fastest GP rider next season, however as impressive as his pace is, my personal observation is his aggressive bike control and the aggressive way of how he back his bike in the corner, could be a draw back on a GP bike, especially in terms of tire wear.
If you want to see a major difference in bike control, take a look at how JL rides and how MM rides.
