Why would the next battery necessarily have significant benefits (other than cost)? What we know is that the current S/X batteries age very well, and much better than those of Leaf/Zoé etc. In any event I don't see a compelling reason (other than perhaps cost) for Tesla to change in the near future, and even less for us to wait for a 2170 battery in S/X.
While I acknowledge 2170s could of course be a failure similar to the 90 kWh pack, I think it is more likely everything Tesla and their battery partners at Panasonic has learned has been poured into this second try. I expect faster charging, faster performance potential, better packing potential (larger packs) and other such possibilities. I don't
know they are there, but I do find them plausible - and IMO much more likely than "only thing that's better is cost". That's IMO not how advancements usually work. Over time things become cheaper and better.
I also don't agree Model S/X are old. Model X is barely two years old. As to the Model S, I can't really imagine how you could improve much on its quite timeless exterior design.
Model Xs interior comes from Model S, though, which is now six years old - well into the total model refresh age for a car. Model Ss exterior, too of course. I agree Model X's exterior is not old yet, but given we're mostly talking interior refresh, that doesn't really matter that much...
The interior doesn't need an overhaul either imo (I can imagine some "nice to have" things being added, like a ski trap/middle armrest for the back seats, some storage space in the doors (how difficult can that be) or even -tadaaa- a couple of free coat hooks
) but otherwise I think, as always, progress will be incremental and behind the scenes (faster UI, adding some more redundancy, higher definition screens, etc.).
I don't know if the interior
needs an overhaul, but I do expect it will get it. That is part of why the current one feels old, it will be replaced soon. Or has been already, with the Model 3 interior. And, well, it
is a bit old.
Also, AR HUD.
Is your two-year old MX so "old" that you would today buy something different? What exactly would you buy that is "less old"? A PowerPoint presentation?
That's a good question. I think for me the Model X wait (reservation in 2014, delivery in 2017) was coming to the stage of take it or leave it when I ordered. I took the chance on one more wait by forgoing the AP1 and taking the AP2. I was and am very happy with the car in the end, as purchased in early 2017. Would I buy the same car today? No, of course not. Tesla has discontinued so many things that matter to me (adaptive spoiler, ventilated seats, Helix wheels, Alcantara dash?) and there is nothing to replace them
yet, AP 2.5 doesn't really excite. And I can't help the feeling that a major refresh is coming soon. It was a good buy in early 2017 and I'll enjoy it for quite some time. Today, I'd wait for interior refresh and/or new battery...
If not a Model S/X? What then. Well, Model 3 would be more modern in some ways, but of course not available here. I guess I would simply wait for all the options to unfold, Jaguar, Audi, Tesla etc. Or perhaps buy that new Audi A8 with comforts for one last ICE. But not now, I like the Model X. A bit smaller second car, that may be a different story...
I'm actually happy I don't have to buy anything today. The choices seem less than optimal IMO. Tesla choices will be significantly better if/when the interior refresh and new battery hit, though.
And so will be the BEV choices from the competition...
