While toy hunting today I found a two pack of (Universe) Cybertron Optimus and Crumplezone. It was overpriced but I put one on laybuy in anticipation of the big toy sales coming soon. My question is, what other sets like this are out there? I did not know this set existed even though I consider myself pretty well informed. I have the Dirg + Roadbuster and Springer + Ratbat sets, but is that all there is? Also was this set an exclusive? I really like some of the Cybertron molds and would be very happy if I could have the chance to buy another Primus at retail.
