It will clearly do well, but there is no where near the perfect storm the first film had. The biggest advantage they have is that it is now a Disney property - basically, they have cleared the slates of any other major titles it would have had been up against if Disney had not purchased Fox and it had some actual competition. If there were, say, a Marvel film opening up around that time, it would be facing a far different landscape.
You are correct, though - that this is not going to get repeat viewings like the last one, and it's not going to be this "wow you have to see this new technology!" cultural event that drew everyone and their grandmother into theaters specifically to see this new fangled digital 3D tech. When you add on the fact that beyond it's technical merits, the original film has very little character recognition or anything else today (almost no one has been waiting a decade just to see what the "next chapter" holds) it is difficult to see it following a similar trajectory of growing the audience versus the steep drop off it will likely have, like most films.
