Spoke with my sales rep today. He said that all M3P delivered from now on will have the new Battery and Ryzen chip. No news about the new hairpin motor or acoustic glass. My guess is in the next month or two.
Since your location says "mobile" could you at least specify what country you are in? This thread has people from multiple countries participating in it, and "all" of them would be interested in that information, but even if its true, its only applicable for the country you are in.
Also, on a side note, I would believe a tesla "SA" about something like this about as much as I would believe any other Car salesperson saying something or other is in a car. In General, Tesla SAs tend to have less information than even someplace like here has, not more.
