The good news for those like me hoping to be able to have the entire Hasbro TFs cartoons on DVD, the last series yet to be officially released will be out December in America.
This follows the recent release of Cybertron, and hopefully we get a RiD US release soon as well, as the UK version is difficult to find (so is the Armada set as well).
