The Optimus with Trailer has been out for a while now. Just yesterday I found Blades with a human figure at Walgreens of all places. Doesn't look like they will be hitting the normal retail shops. I can't remember the name of the human but I know it was the evil doctor from the time travel episode. Now I just have too find the Boulder for that set and I'll be all set.
Yeah, I found Blades w/ human and Boulder w/ human about a month ago at Kohl's.
