Yeah, I agree, all this bickering has become pointless.
Things may become more interesting as the retailers scale up for "Force Friday II" on 1st September.There is certainly quite a bit of information about toys, merchandise and alike sneaking out now, though none of it really leaking anything major about the storylines.
Predicting when the trailer will drop is a bit more difficult. We had to wait until mid October for the first from TFA, but they were really pushed for time on that one, unlike this. But then again the first trailer for R1 dropped early August, just after the BHTS trailer at Celebration and we all know the story behind that production.
I'd certainly like to see a full trailer drop earlier rather than later. Its been a very disappointing summer blockbuster season, no real movie has made any significant impact at all, nothing on any level since "Wonder Woman". Even "Spiderman HC" faded surprisingly fast.
If they leave it to October they are going to knock into "Bladerunner 2049" but then more importantly "Thor Ragnarok". Interest in that is massive , its probably going to be highest grossing movie this year (or second behind TLJ if they are counting the BO into January). If I were Disney I would not want anything stealing the limelight and focus from that.
So if I were them I'd get that first trailer out rather sooner than they did last time.
