Predaking definately isn't in line for a reissue yet. They're focusing on the early well-known characters first, going more for the nostalgia factor than the most demanded by collectors factor. According to most sources, the Dinobots will be next, probably followed by Reflector and some other '84/'85 Autobots (I'm pulling for Sunstreaker and Wheeljack ). The other seeker jets will probably find their way in there as well, and maybe Soundwave's other cassettes. It could take two years to release all this, so don't hold your breath for Predaking
I dunno. To me, Wheeljack is just Sideswipe in cheap plastic. I really never got into Armada because the designs and transformations don't impress me at all. After all, Sideswipe had the least creative transformation of probably all the early G1 Transformers
doing Predaking is a cool idea, but if they do Predaking i think they properly do Computron first..... cos so far that is the hottest item in ebay, the rest of TF just don't worth jack cos of all the reissues!
