Has Rosberg's chance evaporated?

[N. Jones]

I thought Rosberg would have a great opportunity to regain the title lead when Hamilton takes his engine penalty. As it turned out, he is still 2 points behind and Hamilton has weathered the worst case scenario. I suppose the question is, has the opportunity eluded Rosberg?
There is obviously the one remaining reprimand on Hamilton and the potential future upgrade to engine that may play to Rosberg's favor, but that too may turn out to be elusive. With two points behind, can Rosberg pull an Houdini and snatch this years title from Hamilton?

I think his chance depends on Hamilton having some bad luck or making mistake which is rare. What are your thoughts?

No. He will always have a chance so long as he is driving the best car.
