I was one of the people who originally suggest the nocturnal pack coming either in the fall or winter as one of the two dlc left this year, and while I do think it's entirely possible, I also want to throw out that they could do something like a Drylands Animal pack as a counterbalance to the Wetland Animals pack from the spring. That pack was conceived to add a bunch of highly requested animals (platypus, capybara, crane (it's a new type of bird)). Same with the Conservation pack, that added 3 highly requested animals united by a common theme.
A Drylands pack gives a ton of leeway as to what could be added. It could include all types of deserts (arid, xeric, alpine), scrublands/Mediterranean climate, dry tropical forests, savannahs etc. There's a significant amount of animals that are highly requested that fall under that wide of a scope, including Tasmanian devils, wombats, maned wolves, crested porcupines, emus, secretary birds, fossa, coatimundi, certain species of howler monkeys apply, Hamadryas baboons, caracals and so forth.
