With the release of Primus and Unicron being quite some time ago (reissues excepted) we haven't seen a City-Base transformer. it's logical not to have one in the HftD, or the Movie-verse, but there is a little room in the Generations/RTS lines. As much as it is a pipe dream, WfC did have Trypticon and Omega Supreme sitting there, teasing us. We have Supreme Class almost completely disappear from the shelves- IIRC, TFA Optimus and RotF Devastator was the last released in that class. The closest we came to getting a Supreme Class toy was TFA Omega Supreme, but at most, the fans were hoping for him in Leader Class. And Leader Class has been limited to such a small number each year that it there's not room for trying a new idea. So are these the signs that tell us the days of the City-Base transformers are over and gone? are they the dinosaurs of the line?
