Hints of the Cataclysm beta being ever-closer continue to filter in. This time around, art assets for Cataclysm testing phases have begun to appear on Battle.net. While there is still no indication as to when the beta will begin (or if they even have a schedule for their various testing stages themselves at this point), Blizzard is most certainly ramping up their preparations for it.
As always, WoW.com will be keeping a close eye on all developments regarding Cataclysm. When the beta officially begins, we'll make sure you're among the first to know. Until then, continue to be wary of beta-related phishing attempts and other scams. It's coming, but it isn't here yet.
