Very true, however the Illinois Farm exhibit that was originally planned was scrapped and replaced by the Wild Encounters Children's Zoo, a completely different exhibit than what was originally intended. Same goes for the planned Japanese macaque exhibit, which was instead turned into a nature plaza. I get things will change as time goes on, but this shows that its hard to know for sure how strictly the zoo is following this plan, and considering it's been a decade since anything listed here was built its easy to dismiss it as a case of could've, would've, should've.
