Plenty of other posts on the issue in other threads.
Bottom line is that actually nobody knows, there are a huge number of uncertanties in the industry, and the best thing is not to plan for any specific date. It will change. Every manufacturer is in the same situation, new models or old. One of the reasons for the huge bounce in s/h car prices is non-availability new.
I have heard various theories about different colours and spec taking longer etc without much evidence. I am not changing my preferred spec on rumour.
When it is loaded on the boat then I will know it is coming. Until then I believe nothing.
