So I just got off the phone with Tesla and was told that my M3RWD (MSM, aero, black interior) is still penned for an estimated March delivery.
If you are interested in whether or not you'll get the upgrades, or how to shorten the delivery time for your White Model 3, please read on...
I asked the advisor about upgrades and the advisor went away to double-check this before coming back to me and telling me that any M3 car matched from now (incl. RWD) should come with the new features including Ryzen, heated wiper park.
I then asked on behalf you those of you that have ordered a White RWD and the answer that I was given is that the issue is actually the aero wheels and not so much the colour of the paint. Reading between the lines of what was said, as far as I understand, it's something like batches of aero wheels are assigned for different colours and because Midnight Silver Metallic, Blue, Multi-coat Red and Black are not ordered to the same degree, they are more or less OK as far as delivery goes. But, because there are a lot more White orders, they can't keep up with aero allocation. Anyway, I was told that if you have ordered a White RWD and want it to come faster, then changing the wheels to the 19" wheels will accomplish that.
