Not necessarily. I've heard a lot of people (including all of my friends with me here) who WOULD renew their subscription had Blizzard been serious about a new expansion.
You guys have no idea how much of a joke it is here lol. WoW has lost a huge number of subscribers in the past year. So yeah, they're noticing. They know the game is winding down and now they're just having fun with people before they announce Titan.
