I don't think Wizards of the Coast is interested in pulling in 4E groups at all. I think they're more interested in pulling in people that played D&D prior to 4E and then stopped playing or are playing different games. If 5E was designed to make 4E players happy, I wouldn't be interested.
I'm looking to share my room at the Hyatt Hotel. I am looking for up to three people. There are two beds in the room and then two people can sleep on the floor. I'll be there Wed until Sunday.
If you're interested please do not be a smoker.
