My prediction????????-PAIN

Actually I really don't have a good feel for how it is going to end up. It will probably be close between Mercedes, Red Bull, and Ferrari.
Most people are saying that the Mercedes lump in the works car has an advantage. I guess we will see. If so I predict "The Boss" for the WDC.
Let us not discount Red Bull and all their recourses, as well as Seb behind the wheel.

Ferrari may just be up to the task, and if they follow recent form (which there is no reason to expect they will), they may have an advantage in reliability. Gearboxes have to last 6 races this season.
But all in all this is pure speculation.

Come on practice
