Oh yeah, the Lost Kingdom Lizardmen and Mercia ranges are awesome, I've browsed through them and half-drooled before, lol. Mercia is basically everything I dreamt of a revived/updated Bretonnia to be. Alas.
That's a very interesting range with the Highborn elves. The ring element is a neat concept. Probably very divisive, and obviously something you'd take off if you want to approximate GW's high elves, but I can certainly see them as a cool way to make them stand out from GW or other high elf concepts.
