Is this the earliest he's ever started doling out hints? This kind of discussion makes me feel like I've somehow skipped ahead in time.
The fact that they seem to be nabbing the IPs as early as now makes me think that many are probably paying top dollar to get in, and that Potter will be open during HHN. Realistically, HHN would do great attendance without Potter but I think companies really want their name attached alongside what will be SoCal's top tourist destination next year. Day crowds will be just as intense in 2016... don't be surprised if USH finally makes some changes to what day guests see in October.
