It's a real shame, the idea has soooo much potential. The idea if him riding on spirits looks great! It's just way too big and he has no sense of movement or forbodding!
With you - it's a technically amazing plastic model, but it feels soulless (if you'll pardon the pun).
I do like the ghosts/spirit host from this new release, so I will pick some up for my undead army. The rest... nah.
I believe it's a common publishing trick to do small print runs and then say, truthfully, that you've sold out and you're having to reprint. Apparently D&D 4th Edition only covered pre-orders with their first printing, so they were onto their second print run as soon as it was released (with the attendant hype).
So I call bullshit on GW - it's a cheap marketing trick.
