Yikes! I have a differing opinion which is pretty much the norm for me.
Right now, you have a great chance of getting to ride by being there at opening and following directions as outlined in the other thread.
Some inner sense tells me that if this goes to fastpass, and standby, it will be a crazy wait, with fastpass disappearing almost instantly. Plus as the ride becomes known, it will increase in popularity. Seems there is nothing quite like it anywhere except the Disney parks.
Right now, there are visitors who still don't know this ride exists, which gives an edge in getting a boarding group. The pressure to ride will be high for years to come - I don't see the popularity decreasing unless the ride proves unreliable, and Disney is not about to let that happen. This is much bigger (in my opinion) than Avatar, FOP, and the FOP is still 2-3 hours wait mid day.
What's sad to me but I guess good for Disney is now you need fast pass to do rides during the main operating hours - no more slow times.
