Shockwave Lab Weibo have uploaded images of their next product: SL-58/59 Upgrade Kit for Power Of The Primes Rodimus Prime/Unicronus.
These kits are designed and colored for POTP Leader Class Rodimus Prime (SL-58) or Rodimus Unicronus (SL-59). Each kit contains a new pair of more articulated thighs and a pair of shoulder fillers. The thighs parts need some assembly while the shoulder fillers just snap on their position (can also be connected to the thighs for storage).
We still have no concrete information on price or release date, but it should not take long since Shockwave Lab upgrade kits are usually available online once they share images of the product. See the mirrored images after the jump and then share your impressions on the 2005 Boards!
