Again, that is different than saying nothing is going on. It's just not going on as fast as we would like. We do not know anything about the internal workings of who is or isn't interested in Disney Springs, and as far as we are aware, it's on schedule for it's proposed timeline.
Pace is something to talk about, and Universal sure has the hotfoot on to try and capitalize on it's recent successes. But Disney does not need to rush. They have no need to incur the construction costs in one specific timeframe. Right or wrong, they are building at the pace they see fit to build, and along the same pace as nearly every other project they've constructed in recent memory.
People are still coming to Disney in large numbers. People (using the larger sense of the word here) are not giving Disney a reason, yet, to feel the need to advance their construction timelines. At this pace, they will have a completed New Fantasyland, and then a revamped Downtown Disney, and then a fully realized Pandora, each probably around a year apart from each other. That is likely enough to keep "People" coming. If not, they will decide to push ahead with one of the many expansions they have in the can already.
