Based off of Marvel’s current promotional track, it may be easy to pinpoint when exactly the first trailer will drop.
Marvel Studios also confirmed it will be presenting at SDCC this year, so the Saturday Hall H panel could pinpoint the trailer to July 22.
Thor: Ragnarok just dropped its first trailer seven months out, which would put Black Panther‘s first trailer in July if it follows a similar path.
Marvel could very well debut the trailer at D23 — the week after Spider-Man: Homecoming hits theaters — and then show it at SDCC and online simultaneously.
