Bordertown slated for Spring 2015 start?

Up until yesterday, Bordertown was slated to start sometime in 2015, however it was unclear when the series was going to begin. Welp, there was a private screening the other day in Hollywood and a lucky viewer posted this:

Yep, that’s a postcard and on it we get the note that ‘Bordertown’ is expected to premier in Spring 2015. Thought to be honest, with the way Mulaney has been bombing out on FOX, the network may want to start this series sooner because it stars Hank Azaria (The Simpsons) and a slew of other stars that should help turn this one into a hit.
No official word yet as to when Bordertown is going to premier, but it seems as though we may be getting closer.
"There are also other characters that come and go (also owned by the Warner Bros. Discovery conglomerate media company)."
Huh. Is that just referring to other characters from the show itself, or is this implying that the new season is going to have cameos from other WBD IPs
