With EV's it's likely new model cycles will bring vastly more range rendering the outgoing model more obsolete than we have been accustomed to with outgoing generations of ICE vehicles.

I used to think this, but cell progression has been really slow. Tesla's first cells from over a decade ago, the 18650 have an energy density of 240Wh/kg. The newer 2170 are 247Wh/kg and the newest 4680 are 244Wh/kg. So at the cell level, not much has changed. At the pack level it's a bit different story, but I just haven't seen anything that would indicate drastic improvements in the short/medium term.
