There is a lot of talk about how HW3 cannot be retrofitted to HW4. Elon even said so. But it is not really true. The cost is just higher than Tesla would like. A new FSD computer could be designed that fit current cars. This is not a challenge, and there are enough cars to make it worth it. The hard part is the cameras. Upgraded resolution cameras would also not be that hard, the existing wiring almost certainly could be used. But wiring in new cameras would be substantial labor, probably $1000 job (retail). So if Tesla faces large pressure, the cost could be capped at $3000-$4000 per car. Only cars with FSD would be required to be upgraded. Finally, Tesla could offer an FSD owner to give up the rights to an upgrade in exchange for a licence transfer.
HW4 we have seen now, it has different inputs than HW3 (more camera inputs). Tesla would have to specifically build and test a version, AND program FSD differently, for the different HW revision.
Tesla, historically, doesn't do this. If you get stuck on orphaned hardware and software, they will continue to support it as best as possible, but eventually it is legacy, and not supported, and not getting upgraded (a la AP 1.0).
