Agree with most of your list other than Steer-by-Wire and 48v low- volt architecture.
The steer by wire will ultimately be a cost/weight/complexity savings but the yoke really should have been DbW in order to reduce the number of turns lock-to-lock as the Cybertruck is. This is the proper implementation of a race-style yoke. Swapping out a circular wheel for street driving with multiple turns lock-to-lock is stupid. No other way to say it. This one happening in 2024 is a possibility as I believe it's a technology Tesla wants in it's entire line sooner than later.
The 48v is the wave of the future. Not that Tesla has begun making all of their own components via vertical integration there's zero reason to stay with 12v. I'm sure they've got some 3rd party contracts to see out to the end and there will need to be some supply chain and assembly line adjustments to make it a reality in all vehicles but, given how quickly Tesla can do something like build a new Gigafactory now, this is all child's play by comparison. Because of all of this, this is also an update we could see in 2024.
All that said, would I cancel an order of an item I had a need (or at least a want) for due to this conjecture? No way. Even if we know it was coming there's nothing set in stone about just how long it would take to happen. Hell, even if Elon himself said it would be by Q3 2024 I wouldn't make any big plans on it actually happening. We all know how those promises happen.
With Tesla, it will happen when it happens and you're best just buying the best that meets your needs if you have a need/want to buy something.
