Yes, either 1 or 2 hounds... based on if there are 3 Reflectors in the case (with 2 each of Red Alert and Brunt). Entertainment Earth says 2 of each, but another listing that was floating around claimed to have 3 Reflectors in each case, which would mean just 1 Hound. Considering Hound is supposed to be in wave 5 cases as well, I don't think it will be a difficult toy to find by the end of the year.
An confirm the cases at Kmart (well my local anyway) are 2xeach.... so 2 hound present, and I still need to hunt a 3rd reflector
