Distant past for two figures?
Grimlock and Swoop right? Or could they mean in tf lore and be looking at earlier Primes (since Alpha Trion has been done before). If it is Dinobots, with what molds would they be made with?
Rotorstorm needs an update, and I doubt Hasbro could ignore how popular LSotW has been, but given that Springer, Perceptor, Ironfist and Guzzle have all had redecos made in the past few years (and Pyro), that would leave the Jumpstarters, Overlord and perhaps the minor Decepticon characters Snare and Stalker.... Still a set worth getting!
I guess the questions to be asked would be what molds are they limited to? The classics line seems to be the only option since the movie figures are largely no-gos.
