Premeditated illegal attack? Lol, you're really reaching on that one. You think before the race Rossi was sitting with his team planning on running Marc wide? Exactly how much was premeditated? IMO, Rossi never attacked Marc at all... he slowed ran him close to the edge of the track. After that Marc made a decision to turn into Rossi and made contact. Marc simply got the worse of that contact. Rossi was punished for his role in the incident so as far as I'm concerned it's a dead issue.
Rossi is in good shape going into 2016. For the first half of last season he really struggled with his qualifying, but his race pace was excellent. Towards of the of the season he finally started to qualify better. If Rossi can qualify well next year, I like his chances to challenge for the title again.
Except that qualifying better didn't seem to help him, he out qualified Jorge at Sepang after all and couldn't stay ahead of him, and was beaten by Dani Pedrosa in 4 of the last 5 races, despite qualifying better than he did early season. Dani is presumably not going to miss several early season races for arm pump surgery either in 2016, although a different physical malady is always on the cards for that unfortunate rider.
So even if you are correct and VR may be better placed against Jorge, he will have to beat Dani and even more so a highly motivated (significantly by him) MM who showed signs in the second half of the season of being capable of more judicious race strategies.
Anyway, we shall see, that is why they have the races.
