I was admittedly flummoxed by the announcement that the forthcoming Eldar update would round out the remaining Aspect Warriors and Phoenix Lords when that seemed like exactly the kind of specialist unit that you'd want to use to sell Kill Team sets, but sure enough that is exactly what Games Workshop is poised to do.
We've already seen the spicy elf so the rest of his boys aren't much of a surprise. All of these kits have been incredibly faithful to the 2nd Edition sculpts and that remains the case with all three of the Aspects revealed today.
Swooping Hawks have probably benefitted the most from their long delay as the production team learned how best to make "in-flight" poses work for miniature that are very much subject to the laws of gravity. I have already heard some early grousing that people don't like the Asuryani ruins they're posed atop, and to those people I say get good at basing – there is literally nothing stopping you from pinning them to the battlefield detritus of your choice.
Warp Spiders are probably the most changed of the lot, if only because the switch to plastic enables the model to more accurately represent what it was trying to depict in the first place. It does a fantastic job of unscrunching the tiny, hunchbacked pewter models that were limited by the realities of centrifugal casting molten lead.
And of course, Phoenix Lords including for the first time Lhykis the Whispering Web, Phoenix Lord of the Warp Spiders. This has been a hole in the Eldar range since the '90s, so hopefully they make her introduction interesting in the codex.
