Gosh I hope so, 5 years of content would be fantastic. When the game first released I figured 2-3 years of content. Of course, I also was thinking larger expansion, but maybe the numbers will end up the same.I wouldn't be surprised if we have a full 5 years of support, honestly. We have the 5th anniversary, a couple of DLCs, and then that's it. That'll be a solid run for the game. It's definitely longer than Zoo Tycoon 1 (2001-2003) and Zoo Tycoon 2 (2004-2008)
I know I've said that it's almost surely not happening, but there's a small part of me that hopes that if we do get 5 more packs....maybe we will see flying exhibit birds. Likely not, but I can't give up that want completely, even though I have no actual expectations of it now.
