I doubt they'll have the planet, likely it's just for artistic purposes on the model. Unless they intend to build a giant 200 foot tall planet facade just for the purpose of background scenery. Might be possible (hiding the base of the planet behind all the trees and rockwork where it's attached to the ground), but I wouldn't assume it's happening. Would also look very odd in all the other areas of the park where you have a view of the land without the magic of forced perspective.
I'm worried about the boat ride. It's apparently absent from the model and nowhere to be seen yet at the event. The Disney Blog is reporting the rumor that the ride is currently "being reworked" and may not open with the land (delayed until 2018). I hope there's no truth to that, or worse that the boat ride has even perhaps been canceled. But if it is delayed, I pray that they are using that extra time to make the boat ride better. Specifically that it amounts to more than the "C ticket" the early leaked blueprints indicated it would be. It's the only ride i'm really looking forward to at the moment. I don't want any more value engineering garbage, nor stretching out the development to make quarterly reports look better...
