Well it probably has several factors.
1. The only thing going on back then was the Wizarding World Expansion. Now with Cabana Bay, Transformers last year, water park, CityWalk expansion, Kong and JP talk, and possible 5th hotel; there's other areas where forum discussions are going to take place.
2. Phase 1 was the first time anything Potter happened, so the hype obviously is going to be a lot more because no one knew what to expect. It also doesn't help that most of the exciting things are behind the London facade. With Phase 1, we were able to see everything for the most part. With Phase 2, unless it's a chopper, it's been pretty secretive.
