The Sanguinary Guard do look cool. Don't think I can fit them into my Raven Guard though, as they're a bit ornate. Death Company also look cool, even if I think they're a bit cluttered. Still, if I was to use them, I'd mix them with normal marine bits to dull down the Death Company a bit and add more detail to the standard marines. Glad to see Lemartes also has an awesome model after his horrid old one.
Always been interested in Blood Angels, just now have to resist the urge to collect them with their shiny new stuff. However, as a Raven Guard player, I'll be interested to see whether the new rules would allow a good representation of the Raven Guard or not (though I assume standard codex might still be better).
