surely the new indoor accomodation will have indoor viewing along with an indoor pool but with the herd expanding as it is, indoor viewing might not be a priority
My guess is it will be another large barn-like structure like the elephant and white rhino 'indoor' buildings. Both these have indoor public viewing. Neither has an indoor pool but the hippo house does and there they've managed to incorpoate indoor viewing too. The elephant and white rhino 'houses' are not terribly attractive but perfectly functional, so I'd be happy enough if the new Indian rhino quarters were similar...
