They were on last week's episode actually, pictured next to Rex, but in darkness so hard to make out the coloration.
I still wish someone could somehow confirm if any of these figures were made in US packaging or not. I still think these could really be hard to come by on the aftermarket otherwise.
A lot of people are speculating that the animated Rex and the BD pictured with the Mission Series figures at Toy Fair were just place holders and different versions will be released eventually. Guess we'll have to wait and see...
