Any insights on when 2023 EQB 350 can be ordered?

I put a deposit it with the dealer (Fletcher Jones So Cal) for the '23 EQB 350. Waited several weeks and was told that the order was still in the order bank and still has not been released. The dealer hasn't heard back from the factory and suspects that the factories are prioritizing the 250s and 300s, and could delay the 350s. Anyone have insights on this?
