As the fourth wave of Legions and Cmdrs have appeared in Asia, photos of them with their previous versions have been posted up on a HK site and mirrored here.
Note that all 5 are just redecos, which is probably why there hasn't been much excitement for this wave. (especially here, since we are still yet to have Wave 2 of each size class appear in most stores)

Legions
Tailgate is a redeco of Cliffjumper
Fallback (Outback) is a redeco of Breakdown
Knock Out is a redeco of the Vehicle Set figure

Commanders
Dreadwing is a redeco of Dreadwing
Battle Tactics Bulkhead is a redeco of Bulkhead

Four of the five Wave 3 figures were just redecos too, so there aren't a lot of new moulds for a while.
