Currently there aren't any teasers/trailers for season 2, however I'm guessing there may be one in fall. For the record, there is also a blog on this wiki with official sources to back my previous points up. We do know that a season 2 is in the works, it's just a matter of "how long" now. Sorry about that ¯\_(ツ)_/¯.
