I like your unbridled positivity... How have you made it this long on the board???
In response to your actual question, I have some thoughts...
1. Avatar Land will initially be successful, especially with the Release of Avatar 2. I do believe a 3rd ride would be prudent.
2. Star Wars Land... How can it go wrong? I think 14 acres might be too small to devote to such a HUGE franchise, and will need expansion soon rather than later. I would love to see a Giant Death Star anchoring the Southeast corner of DHS (It would make sense, they've already got the plans with SSE).
3. Toy Story Land will be good for a little while, and grow again once 4 comes out in 18. Slinky Dog will be a hit with the kiddies, Meh for the adults.
4. I don't know.
5. I wish I was an Imagineer, I have tons of concepts to improve/expand DHS, EPCOT and MK (Tomorrowland/Adventureland expansion), including many ideas that incorporate everybody's favorite IP's, since that is where WDO wants to focus. Any time you're ready, Mr's. Weis and Connelly!
6. WDW and all of Disney will continue to grow, inspire, and above all, make money. Regardless of how many people say their experience was "unmagical" (Looking at you
@katiebug). Heck, I'm 36 and was inspired beyond belief after my most recent trip, revisiting my 12 year old dream of wanting to be an Imagineer. Imagine what is happening in the mind of someone much younger and more impressionable...
