Lol!
For a reasonable company it only makes any sense that they dropped the old hardware, disabled paid features but continued to sell them, and promised only a short gap period if they were very far along with the solution. They'd have to fully understand the task, understand the path to a solution and be well along it - problem fundamentally solved, system working, just finishing touches and some final verification testing to do. If that was the case they should absolutely be able to give a timeline and have a good chance of meeting it.
The fact the gap has been 5 months and counting and they are still being vague with no timeline offered, and making statements with the same language they use for FSD/robotaxis, suggests a far worse reality - that in fact this started with a memo from the top simply saying 'we aren't fitting USS anymore, you need to do it with the cameras, get to work' and they have no idea when or even if they can solve it. They are essentially engaged in a research project. If that's the case this shambles is only getting worse.
