Good eye. Well that's exciting, good to know the girls won't have to wait for years until their knew home is built. Well... if they're even going to be a part of the Elephant Trek anyways.
I wholeheartedly agree. I was concerned that Mai-Thai and Schottzie might not live to see Elephant Trek's completion, so I am very glad they will still get to enjoy more space and a more engaging environment in their golden years even if they do not.
As far as the rhino/zebra mix goes, the caption on the rendering reads: "Plans for this area also include a larger, mixed species yard, expanded moats and visitor viewing decks." They do not explicitly state which species will be mixed, so it could be possible that the species being mixed in have not yet been revealed.Even in the renderings, the rhinos and zebras are not shown sharing the same space.
