I have never understood where the expectation of more then 2 rides in a new land comes from. Look at the opening day attraction list for Magic Kingdom. Adventureland had one ride, Fontierland one if you count the canoes, Tomorrowland three if you count the skyway and Flight to the Moon. Look at AK today, Africa has one, Asia two. Look at the recent new lands, Cars Land three (two of which are small flat rides), Toy Story Land two, going over to universal, Hogsmede one new and two re-themes, Diagon Alley two if you count the train.
What is the latest ride built purely for expansion, not replacement of others? Tron is the only purely new attraction, New Fantasyland was new, but we lost Snow White to get 7DMT. Even Star Wars will replace old areas. Sure, it's welcome to get new attractions, but they aren't expanding anything. I believe the new model is to try 2 attractions and see what happens.
I know it can't all be in one run, but this is a new era of management. You pretty much get what you get until there are massive widespread changes announced. It's been a while since we've seen an announcement of a new ride in an existing land.
I do love Pandora but adding 2 more attractions wouldn't have hurt, particularly since NRJ is somewhat forgettable.
