This is a repost of what I said in the Star Wars thread, but it applies to your question, I think:
One approach that Disney is taking, and it worked for Cars Land, is to make the area itself an explorable, interactive attraction. So much to look at, see, and do, that you can spend hours there--NOT standing in a line, and enjoying the experience. The land itself is an extra E-ticket. This is obviously what they're doing with Avatar, and with Star Wars. Magic Bands, whatever our opinion of them, will add an extra level of personal interactivity. I think this all started with the Kim Possible thing at Epcot. With my family--we spent hours, essentially just wandering around Epcot, having fun, and it required a minimum of infrastructure changes. Not an E-ticket in the traditional sense--but think about that, we were experiencing an attraction--continuously--for hours, without ever standing in a line. I think this is deliberate strategy on their part, and we'll need to realign our thinking so we're not going 'oh, only 2 rides?'
Of course, this is coming from a guy who does the animal trails, or the paths around the Tree of Life in AK and thinks they are great attractions, so your mileage may vary.
