eh... you are alpha or beta in your head. And for all "loaders works fine", ofc they do signatures are not avilable yet for WAT not because WAT would be beta or alpha or whatever... And if you check WAT signatures you would see it was signed on 12th of jan. You think MS makes something and then just releases it to public without extensive testing? Find it funny how basicaly exactly after a month after signing this WAT and testing there was a "blog" about being released in couple of days. We will get exactly this on 16th, except signatures will be avilable as well.
