So, I don't follow data trends, I don't have any data analyses to offer, I hate numbers and don't care enough to be bothered. But I am 1. a big (though not quite rabid) Star Wars fan, 2. a Floridian, and 3. a WDW regular for the past 30 years. My views on crowds, etc. are purely anecdotal... but also based on having seen the way things ebb and flow down here in the Sunshine State for a long time.
I was one of the few who never expected GE's opening to be the madhouse most predicted. I guess that was based on experience, but I'd be hard-pressed to provide any more detail than that. I strongly suspect SW love isn't big enough/strong enough/rampant enough to clog an entire section of a park 'round the clock, 365. And to say it's the off-season here in Florida right now would be a gross understatement: it's as dead as it gets. (Thank all that is good, because honestly, we need a break from the madness sometimes!) If it's slow everywhere, I can't see any reason why it wouldn't be slower, compared to busier times of year, at GE, too.
I'm not at all sure there are that many families planning entire trips around the advent of GE, but I am quite sure a good many folks who were planning a trip anyway opted to make it at a time when all of GE is up and running. I would not be surprised to see a good bump up in visitors when ROTR is open. If I didn't live nearby, I'd have waited for that, too.
So a quiet-ish GE right now is entirely what I expected and not at all surprising. I think it'll get busier along with everything else getting busier as we head into tourist season (fall) and, especially, holiday season. MFSR's wait times are influenced by the lack of FP, too, coupled with an extremely efficient turnover. I fully expect to see standby waits climb when overall crowds swell and FP begins. As a local who won't ever have the advantage of a 14-day lead time for FP+, I'm riding it as often as I can before that happens!
I am worried that WDW will drop some support for GE over time, and it saddens me to say I think it's probably inevitable. That just seems to be the general direction WDW is going nowadays, and I can't see GE being spared just because Star Wars.
