IDK - Doing this 3 months out? Seems a bit desperate and I LOVED PeaceMaker S1 and am happy this version of the character will be in the 'new' DCU - but I think somebody is nervous.
Love Peacemaker, this show is just bonkers crazy

I don't know if 3 months out trailer is a sign of anything, much less being nervous. It feels like the right time and closer to release they will amp it up with small clips and maybe another trailer, the usual.
