The only thing might be that if the 6-speeds are already on-hand, and not dependent on transmission controllers... where the automatics are more susceptible to the shortage of silicon, and being sub-contracted from another company... the "launch" allocations of the first few units to each dealer may start out as 6-speed cars, with the autos following slightly behind them. They'll likely sell anyway, and get people to see them, and put their name in the books for an automatic allocation at least.
I just hope there is a cross reference for a steering wheel that doesn't have the piano-black plastic touch surfaces, or the oddly glossy airbag cover.
