From the leaks we have these potential Wreckers toys...

Legacy Wreckers deluxe Impactor
Legacy Wreckers deluxe Twintwist (saltman)
Legacy Wreckers deluxe Topspin (saltman)
Legacy Wreckers deluxe Leadfoot
Legacy Wreckers voyager Springer
Legacy wreckers voyager Bulkhead redeco

I would expect Topspin and Twintwist to be together in a 2-pack, which would leave the others to make up the five packs (with Impactor and Leadfoot having some other random unknown added to the pack).

I really don't see the point or need for adding a new unknown character to the iconic concept of the Wreckers, as if they couldn't think of releasing any other Deluxe redeco with Impactor that had some existing relationship to the classic Wreckers team. I guess if Hasbro wanted the Deluxe toys to be 2-packs to maintain the same price-point between them, they didn't really have any other classic Wreckers characters in Deluxe size. The Triplechangers, Roadbuster and Whirl were all Voyager sized toys in Generations... but I guess if they have Leadfoot and Bulkhead included, they could have grabbed Wreckers from any generation, and there have been LOTS of them over the years.

I guess Amazon likes having these themed sets, as we had the Golden Disk set and the Galactic Odyssey set... and each time the release was not handled very smoothly - either some didn't get released outside of America, or they had a sporadic global release making them scalper bait.
