My guess is either something south-east asian-perhaps fishing cat?, or they're putting the wildcat on display (unlikely), or it's going to be used for the cheetahs again.
Given how large the enclosure looks and how it is furnished, this would maybe not a very bad guess... It looks way too large for most of the "small" cats and it won't keep leopards inside with this fence, so sizewise something in between is what I would expect.
I'm not going to play the guessing game - but remember that these enclosures are roofless. Species that specialise in climbing need not apply for this accommodation.
