I agree with all of this. My post is based on the assumption that Avatar and, to a greater extent, Star Wars will continue to be hugely popular but certainly not at the levels we're seeing on opening day.
Either way, guests aren't really "turned away" from experiencing the Disney product. If they can't get into Pandora, they have the rest of AK to explore. If AK is too crowded as a whole, there are three other parks and tons of resorts to experience. As long as those things deliver positive experiences, the impact of the new "draw" lands will be greater than guests' specific reactions to the lands themselves. In other words, come for Pandora, stay for Walt Disney World.
I think the caveat to that though would be that they might be upset if they based their vacation around being at Pandora for opening day and couldn't get in. Then again, they should have expected this sort of crowd if they did.
