I agree. It's only some crazy theories rattling around in my head, based off of one short story (although I do think GW is going to do something through that story). But GW didn't come out with AoS just to say, "okay, let's keep making the same models for the same armies we've always had." Clearly GW wanted to make a change, and they have (not that I totally agree with it, b/c I really dug the Old World). I just wonder if they want Seraphon to stay like they are, or change them so they have more flexibility going forward in AoS?
Maybe GW considers space lizards a big enough change that they'll stand strong with Seraphon flavor and lore. I mean, orks & goblins are basically the same, chaos seems pretty similar, and undead has some new models but feels the same. Even Skaven are coming back up. So far, Empire, Bretonnians and classic Elves & Dwarves are the most in limbo. So, I guess we'll see.
