Well as of this morning the old Wrath of the Lich King Beta website no longer works!!!(about time )
I don't know if we had a BC beta test, or when if the webpage went down just before Wrath but what I do know is that this isnt normal for blizzard. They still have the old Launcher news page on there servers - there not in the habit of a spring clean!
Heres the link if you want it: Clicky!
Read into this what you want, but my guess is that we will get the Beta soon, however this does mean noone leaked the alpha
Have fun
