so while reading the lizardmen thread over in the grand battles section, i started thinking about where the Lizardmen of the fantasy range could go in future expansion sets.
an obvious one would be another infantry set with additional weapon options. say Axes/swords/clubs and shields for the fantasy side (perhaps with some 'commander/hero' bits as well), and blunderbusses plus some RPG's and LMG's for the scifi side. (maybe an arm with a satchel charge/explosive mine or the like?)
i can't really see them having a "heavy weapons team" type set (can't really think of a fantasy seige weapon that would fit, and the weirdwar/scifi options would basically just be cannons you could proxy easily enough)
how about Cavalry? obviously lizardmen would be riding bigger prehistoric animals of some kind. i'm wary of jumping directly to dinosaurs, given GW's extensive use of them for their Lizardmen/Seraphon, but that is a popular trope.
perhaps give them something like a small ceratopsian, or some sort of midget sauropods? i'd personally think that avoiding raptors would be a good idea for such a set. a little bit too common a trope.
personally i'd go with a ceratopsian of some kind. say, Centrosaurus sized. (IE a little bigger than a rhino) could serve as their society's equivilent of oxen as far as usefullness for pulling and carrying stuff, but could be used in battle a bit like a small war elephant, able to charge into enemies. maybe have them carry two riders.. one mahout, one warrior with a long spear or a bow. probably no howdah though.
you'd just want to make sure the arms are interchangeable with the infantry box, for extra build options.
(main reason to go for a smaller dino btw would be to ensure you can fit the parts onto a single sprue, or even a half sprue. so you can fit plenty into the box)
