Dual AOA failure may still trigger MCAS, depending on the failure scenario. And we've seen dual AOA failures (both failing the same way) on real flights several times already.
Having said that, assuming MCAS will only operate once, then IMHO it's no worse than a runaway stab trim. So I don't believe additional sim training will be made mandatory, unless the current runaway stab trim training is also deemed not sufficient (presumably covering both NG and MAX types).
