Alright, this is only the ghost of a hint, but at this point I'll take what I can get with anything that looks reminiscent of a Wrath of the Lich King beta. A tipster known only as "Anonymous" wrote in to let us know that the URL http://beta.worldofwarcraft.com is active, and redirects to http://beta.worldofwarcraft.com/game/character-copy.html. The logical conclusion is that this page is meant to let (authorized) people transfer characters for some sort of beta. And what's coming up that might be beta-tested? Wrath.
Right now, the address returns a "403 Forbidden" page, but obviously, someone at Blizzard HQ bothered to set up the "beta" subdomain and make it redirect to something. Any address on beta.worldofwarcraft.com seems to redirects to that "character-copy" page. Remember, a "forbidden" URL was our first real confirmation that Wrath of the Lich King was going to be the title of the expansion, so we've gotten information this way before. There's still no telling how long it'll take until a beta is available to us, as this page may well just apply to an interior beta, but this might be a clue that we're getting closer. Does this mean there won't be a patch 2.5?
