WWDC tickets sold out in under 2 minutes.
I’ve heard many suggestions for how Apple could solve this problem: find a larger venue, raise the price of the tickets, have two WWDCs back to back, split off the Mac and iOS tracks to be in different venues, or split off the gaming-centric tracks to be in a different venue.
Apple knows demand for WWDC attendance is high, and they knew they were going to sell out in a matter of minutes. Yet they still haven’t yet changed anything related to the supply and demand. For whatever reason, Apple still considers the location, capacity, and structure of WWDC to be the best choice. And so it’s the way it is and that’s that.
The way they draw a line in the sand regarding software and hardware features — waiting to add or change something until they’ve found the ideal solution — is the same way they feel about developer conferences.
