Watching the Direct again, I noticed that the island name here is longer than just 8 characters:
In fact, the name "Nintenland" has 10 characters. Back in New Leaf, the character limit was 8, so maybe this is a hint that we can have a longer name for our town/island this time? At least I hope they not choose that name just for the Direct... What do you think?
YES I think we can safely say that there's a character extension from looking at that! The names I have in mind are under 9 characters but this is great news!
Thank you! The number of letters allowed was my main unanswered question after watching the Direct, and I think this is a good indication that we can have longer island names.
