There are different situations.I don't know where your info is coming from but my Bronco has crossed model years and I have an email from ford promising to hold price.
The guy Ice Capades on Blue Oval and Zach from Granger(ford-truck, tremor forum, etc...) have both said the super duty will not and has never automatically rolled to the next model year. I think it was for 2020 orders Ford either price protected or gave buyers like a 2000 rebate towards a 2021 because of all the Covid shut downs. I dont think Ford did that for 2021's that didnt get built by the time 2022 production started(or maybe they did)... But the orders have all been cancelled and you re-order and start the wait all over again. NOW if a dealer does it behind the scenes and never tells the customer, thats a different matter.
Bronco might be handled differently. Sounds like it is. I think thats a different animal that Ford has just really shit the bed on... and obviously a lot of commodity constraints.
Corvette has taken the path the Super Duty has, but people are getting fucked on the pricing as GM has done nothing to my knowledge to price protect anybody. 2020 was almost 10k short... fucked... 2021 I think was short again...fucked.
