I visited it yesterday, I believe right after the site was "open" to business. lol The game Dark Arts Defence had no "coming soon" sign and one could play. However, it was very slow. I thought it was my computer, but as today there is this new sign and it is not available, I believe it must have been an error of the site.
Anyway, WB always makes impressive websites and this one is no different. I loved everything about it and hope new features are available soon.
