With just two months to publication (two months tomorrow, in fact) HarperCollins Voyager have decided to change the cover artwork for A Dance with Dragons. They are keeping the same style - the book will still sit comfortably next to your Feast for Crows hardcover - but have switched the image to match the US edition.
That seems okay. The sword image was a bit old now anyway and the detail on the shield is impressive. Not so sure about the cream colour though. I think the two US versions (orange and silver) may be a little bit more interesting, but this works well enough.
