JKF was talking about the AF Anakin's Podracer being done in prototype form before the Sebulba's Podracer was on shelves, said his son was playing with that pod at the opening of the film IIRC. I don't think "collect all 4" is anything more than a safety net, so each wave won't have to risk future waves not making it to market (although this DID happen with the pod packs).
As I understand it, Hasbro did the buyout and moved Galoob a few miles down the road to new San Francisco offices. There, they were given extra tasks like designing half of the POTJ line of action figures as well as more Micro Machines work like continued designing of SWMM, creating models for ILM and Lucasarts, and intergrating military MM into the GI Joe name. Galoob division continued these west-coast operations right up until Hasbro recalled both Galoob and Kenner divisions back to Rhode Island, having the San Francisco and Cincinatti offices close up shop.
