Harlequin Skyweavers Were on the GW Webstore
Apparently the Harlequin Skyweavers appeared briefly on the Games Workshop Webstore over the night, (not there now when I went over and checked.) However, the eternal vigilance of the community caught a snapshot of it.
Too bad there wasn't at least an image for them. I suppose they are just working on getting them added to the webstore for release tomorrow.
