It would be a waste of time for them to talk about FCP/Logic for iPad software more than the video they made and have already released to the public. Of course, they might also have another event between June and September to go over the new iPad models.
I think they only released that video because they already have a lot to announce at WWDC, otherwise that video could easily have been a part of the WWDC keynote. I'm not sure if Apple have ever announced iPad's at WWDC. Wasn't it only in October of last year (2022) that they announced the new iPad Pros?
