Not to crash the party a little bit, but guys, the update said "announcement", and not "trailer".
Just to keep a foot or both on the ground, in case we get a video update of some kind from Yu-san, which could very well be what the image is implying. Hence the "now editing" comment...
This is how people get upset over the most trivial things, and if we get a video of Yu-san talking to the camera and does announce something as amazing as a release date, but no trailer, then people get upset because there was no trailer and forget about the good news a release date would be.
Always keep the expectations in check people.
