> They will probably support CCS for a while
NACS is CCS with a different plug on the end. Tesla's charging standard is to die off, CCS will be the standard going forward.
Here's a real world demonstration of a charger with J3400 plugs (aka Tesla's plug):

It works on a Chevy Bolt because it is CCS.
Tesla version 3 superchargers already use CCS for communication between car and charger for 2019 and later vehicles.
Version 2 superchargers do not speak CCS and won't ever be opened to non-Tesla vehicles and there are certain routes where that's quite annoying. My most common road trip has 5 supercharger locations along the way with 3 of them being V2, including the most isolated charger. Even once the NACS changeover happens taking a non-tesla on that journey will be a real pain.
Tesla has not put any resources into converting V2 sites into V3s. Some of the locations have been expanded with the new additions being V3, but I haven't seen much in the way of switchover.
Older Teslas (approx 2019 and older) need a hardware update.
No compatibility break as far as I know. I believe V3 superchargers speak CCS to 2019 and newer cars and fallback to the older Tesla-proprietary communication if necessary.
So what does this mean for a Tesla on an NACS charger? Do they already support CCS over that port, or is it a software update?
I know Teslas were already CCS in Europe, so I wouldn't be surprised if the software is already basically there.
