This was linked up in the comment section of the site, and it appears that this week's releases have pages already set up for them on the Games Workshop Webstore. These releases are not really a rumor at this point, as I have heard specifically from several different sources of their coming this week. This is just another confirmation on their releases. Atia on Bolter and Chainsword has been on it when these are appear.
Please remember that these are url changes. Of course they show up as generic error pages, but its the auto correction when typing these in that show something is being done.
