I would suspect that BMW would be second only to Honda in the amount of money they could throw at the problem of building a MotoGP bike. And after Valentino Rossi wins the championship two or three times on the Yamaha, and his contract runs out, he'll be looking for a new challenge. I thought I heard a rumor around the time that BMW announced the K1200S that they were thinking of building a MotoGP entrant (I would think homologation rules would make it difficult for them to enter WSB unless they decided to build a shorter-wheelbase, smaller engined production variant of the K1200S). Pair up BMW's deep pockets, and Rossi's incredible abilities, and you could see BMW sitting on top of a premier class podium in a few years.
Speaking of Rossi and MotoGP, what were the odds that the two riders tied for first place in the points-running would both crash out in the same race? When Sete Gibernau crashed, I figured that the championship was basically over, and that Rossi was virtually untouchable as long as he finished on the podium in the rest of the races. Then Rossi crashed out, and the season looked wide-open again. My money's still on The Doctor, but I think this will make the rest of the season that much more exciting.
