MY24 reveal is on 9/14/22. I’m pretty sure they will announce when they will go on sale either at the reveal or shortly thereafter. On the other hand, the MY23 is basically a known entity and the order bank opens up on 9/21 with them rolling off the assembly line starting around thanksgiving.
Since I haven't seen it posted here, the 2023 order guide is available. Obviously nothing really changed aside from the black accent package changing to Nite Pony and Britteny Blue and Cyber Orange being deleted, but I did notice the last call for EB HPP option deadline is November 15th. Mach 1 handling package production also starts in March. By the looks of things, 7th gen integration and changeover may be soon.
Really wanting to wait for 7th gen pricing, but may throw an order in for an eruption green GT just in case seeing as the new Super Duties got a huge $10k price increase less "mArKeT aDjUsTmEnT".
