Given how poorly they've handled the PR campaign for this there was already a risk that next month's unveiling would underwhelm.
A cinematic trailer which we know every detail of and have pretty much seen screenshots for isn't going to do wonders, is it.
It's supposed to be.
They better not pull another "look at that amazing airplane crash with terrain deformation and all that" in trailer only for it not to happen ingame, no need for a battlefield V repeat.
