Just judging by Toto's post race comments, I think that it's VERY likely. My guess is, Lauda will want to let them continue battling, but with greater team penalties if they do bad things. I'm not sure who will win, assuming Lauda puts up a fight. Plus, Hamilton will likely have a power unit grid penalty or two before the season is over with. So being unable to race for the lead will likely hurt him the most - at least in a couple of races.
