It’s first time that new commander doesn’t announce trailer.
The past three times of blizzcon(16,17,18) announced trailer of commander on the first day.
Of course, maybe coop development team was busy or something we didn’t know.
Personally, I’ve been waiting for this day, so I feel sorry for it.
There’s a normal trailer coming, just not at blizzcon (probably because Mengsk is coming in like, two-three weeks anyway).
He’s got a full talents/unit roster/playstyle thing up in the news section of the site, and the blizzcon pylon show had monk talk a little more about him + show off a couple clips (a recreation of the hots intro ultralisk vs Viking, and a show off of the tankivac mechanic) though
There’s already a thread on this, not sure how you missed it:
