Here's what's gonna probably take place, according to things I've read:
1. Smaller venue, possibly hotel. No longer at the convention center.
2. Takes place in July as stated earlier; allows for more people to get something ready for the show.
3. More intimate settings so that business can be conducted in a sane fashion.
4. Invitation only. So, you're gonna have to probably be a journalist from a reputable place or in another relevant part of the industry. This will yield no more than 10,000 people attending.
5. Reduces cost for companies in a high-cost era of game development.
