Fourzerotwo" Bowling is warning of fake Call of Duty 5 beta invites being sent out. Mr. Two states that if you happen to receive one of the invites, "just delete it." The email is an "exact replica" of invites sent our for the CoD4 beta, with all pertinent parts updated for the hoax.
Bowling clarifies that there is currently no beta for the game, and if there was he'd be "screaming it from every internet rooftop." For the record: So would we.
