Hello,
I would like to second Nemo's request for timely updates. Unless I missed something (which is very possible), I haven't seen any official news since the announcement weeks ago that the in-person event was sold out.
I imagine I am not the only one about to finalize my summer travel based on the current assumption that I can't attend Wikimania (something I am very disappointed about, but I can accept).
If, by some twist of good fortune, some of us currently on the waitlist ended up getting an invitation to attend, learning about it after our other travel arrangements are made would be adding insult to injury.
As Wikimedians, we are all aware of how harmful lack of reliable information can be. Something as simple as "if you haven't heard from us by April 30, you can be certain you won't be able to attend" would go a long way to reduce uncertainty.
Thanks,
