Well, first off a little disappointed that they didn't take the opportunity to re-do the CSM's themselves - the ones from the Dark Vengeance box had my hopes up but no, same old same old.
The Helldrake; like the idea, not so much the execution, even though it looks like it could be a fun model to put together/mess about with. The raptors looks quite good, and happy of course to have some plastic raptors. Peeved that they went with finecast for the havoks. Love the quality the material gives but can you imagine trying to get a full squad of perfectly cast models? Also, lack of options? Mutilators/Obliterators nice to be able to pick up three in one sitting, and I guess they'll look good made from finecast, but again, lots of issues with the cast and good lord are they pricey.
Hmm, what's left? The characters look quite cool, especially the Warsmith. Like the look of the new Codex. And the Forgefiend thing looks like it could be fun to build/convert.
Just my two pennies.
EDIT: Is it me or does the aspiring champion look like he should have been included in the Dark Vengeance limited box set? The style, paint scheme and the fact it's plastic would see to suggest this.
