When is the Pittsburgh Zoo rebuilding the reptile house?

I asked a zoo employee and they said that when they had enough funding they would rebuild the reptile house or " Reptile Tunnel " Somewhere were they used to have buffalo on a hill somewhere their. They tore it down to build the waters edge exhibit where the sharks and stuff is. How much longer until it returns, I can't wait much longer. It was the best part of the zoo!When is the Pittsburgh Zoo rebuilding the reptile house?
Right now most of their reptiles are in the Discovery Pavilion (right before the barnyard animals and sea lions in Kids Kingdom. The hoofed animals used to be between the bears and the aquarium. It's just a hillside now. If they couldn't even get a walrus for their Water's Edge exhibit, I doubt they'll rebuild the reptile house.When is the Pittsburgh Zoo rebuilding the reptile house?
If their response was "when we have enough funding" I wouldn't hold my breath for it.
