Alright I guess I'll throw my 2 cents at this speculation...
March 17 (Thursday) - Update Special Feature Reveal (plz variable exhibit sizes!

)
March 23 (Next Wednesday) - Update 1.9 Announcement
March 24 (That Thursday) - Central American Animal Pack Reveal (I really like
@darthquell's idea! I'm on board!)
March 25-April 3 - Animal Reveals (with a few days off for polls, voting, etc. I really hope they do something like the N.A. Animal Pack reveals with the roadmap!)
April 4 - Developer Journal
April 5 - Update 1.9 and Central American Animal Pack Release
With the animal pack, just give me a collared peccary and a white-nosed coati and I'm good. I'm down with the Central America Animal Pack idea because I'm all in with the North American animals, with mods of course (50 N.A. animals!) and I would like to have some more official N.A. animals that stretch into the U.S. Sidenote: Yes I know that Central America is technically N.A. but I'm focusing on the Neartic Bio Realm, which only stretches into Northern Mexico. Anyway, I've gone off on a too much of a tangent. DLC hype season!
