Yes. There is no mention of it on Summit's website, Facebook, or Twitter account. Even that link you provided has been removed by Summit Entertainment. Any website claiming that it is the official Breaking Dawn trailer from Summit is lying. Nothing official will be online until it premieres tonight.
