Are these really Deathly Hallows teasers? I don't know what to think, but my friends sure think he's right on.

There's this guy over at http://www.allforums.net/showthread.php?t=26817 who claims to work with Deathly Hallows and that he's actually reading the book. RIght now their putting up some spoilers, and I'm wondering what the general consensus is. For instance, they said that we already know what "Deathly Hallows" means from books 5 and 6, and that there is a huge hint about the outcome of book 7 from the cover of book one. My friends are starting to tell everyone about the thread (one of them got me into the books in the first place) and they're just going nuts! Tell me what you guys think!
