For reference, the larger CA-based D23 Expos were originally run in odd-numbered years and the smaller FL-based Destination D events were held in even-numbered years, so the Expo would have logically landed in Anaheim for 2023 for the 100 year anniversary of the company.
However, the pandemic meant no events were held in 2020 or 2021 and rather than just picking up with the smaller FL event in 2022 and having the bigger CA event in 2023, someone made the decision to run the missed 2021 Expo in CA in 2022, which threw off all future events on the calendar. So FL wound up with the small event for 2023 instead of CA's large convention which originally would have had it. Doesn't make sense to me to have done it that way, but obviously it made sense to someone at Disney.
