They seem to remind me a good bit of the Hordika series, actually, with the spider mask things. I'm also fairly reminded of 2001-2003 and how much of a knight these new sets look, especially the Toa. There is also an interesting reminder of how 'complex' the building was back when cogs and gears were used (Which I really, really, really geeked over when I opened my shiny new and first ever Tahu), and yet the over all design is incredibly simple and very interesting. Oh, the arm pieces remind me of the Toa Mata for sure. Honestly, this reminds me of a fair bit.
