It seems that no FSD features will be introduced ahead of the chip. My expectation was that FSD would be introduced feature by feature.
I am not sure about that. It was, what a month ago, that he tweeted FSD features would start appearing in V9 and I assume he is aware of all if product roadmaps and dependencies. I would imagine we will still get a drip-drip of features even on the current HW and the "wow" features won't happen until HW 3.0. Remember, there is no regulatory framework in place yet to allow consumer-owned autonomous vehicle of any flavor on public roads (at least in the US), so its not like there is any big hurry.
I would not read too much into the tweet. I think too many people were checking the FSD box without reading the fine print and then creating a customer service headache when their new car wold not drive them to Starbuck.
That being said, I would expect most of the spin on this to be negative, seeing it as an admission that Tesla doesn't have the technical chops to pull of FSD.
