Yeah, way before the Fourth. Traditionally, at least. That said, there are currently multiple spots running on TV (sans a release date) and this past week especially has seen a ton of cast interviews, social media content, etc. Also, check out the quote a few posts above where Nolan and Emma Thompson discuss the release for the first time publicly. The impression I'm getting is that it's sounding less and less like a case of it having to be July 17 or else it gets pushed back to the fall/end of the year. They're basically saying, when theaters are ready, they'll be ready. And because the theatrical landscape is so in flux right now, it could simply be more of a play-it-by-ear scenario, where maybe it hits, say, the first week of August instead. I could be wrong, but it's looking to me like they're going to continue the marketing push as is, and then whenever they can finally nail down an exact date, they'll simply make an announcement and start adding that date to the ongoing marketing, even if that date might be a week or two or three after the 17th, hypothetically. Granted, that would of course affect Wonder Woman 1984's mid-August release (another Warner Bros. movie), but again, maybe, given the landscape, they could easily shift that one back a couple weeks as well. Or, heck, maybe even have both out at the same time. It's the Wild West right now, so anything seems possible.
