Our family is looking at MY24 Ford Expedition as well. Our current Honda is from 2006 and Lexus from 2005. Way too old and is experiencing issues.
The last 2 redesigns looking at Ford's media website, was 2020 and 2022 (and info was always released at the end of September the year before). If it keeps following the pattern 2024 would be the next redesign. While the 2024 build & price is live, there is no mention of it on the Ford media website, which makes me think they are releasing things little by little to build hype. Also it looks like they just changed 2023 to 2024, and haven't gotten around to updating things yet. I mean BlueCruise 1.2 is out, I seriously doubt the 2024MY Ford Expedition Platinum is only shipping with BlueCruise 1.0 as they claim on the vehicle details.
If I were you, I'd wait and see, at least until the end of September 2023 when they release information about the Expeditions if a redesign is in place. Not that far off now.
