Numbers support players returning to World of Warcraft

From Massively:

With the recent launch of World of Warcraft's second expansion, Wrath of the Lich King, industry watchers have been poring over the numbers, trying to see what can be gleaned from the data. With 2.8 million copies sold in the first 24 hours, Blizzard's 800-pound-gorilla continues to break records. Following the flood of numbers, our friends over at GamerDNA have just come out with their own Wrath reports, based on their member data from anywhere between a few days to a few months before Wrath's launch.

As expected, there was an increase in the number of returning players, out to experience all that Wrath has to offer. We admit we're curious about potential skewing of the numbers, though. On the surface, it would be largely what one would expect - Wrath launches, the numbers went up. However, we'd note that they started running a World of Warcraft-themed contest for Razer gear on the 12th, and a SwagDog guild promotion on the 19th that may account for at least a small portion of the metric increase; how much of a difference remains to be seen. Also noted is the number of WoW pages created on their service after the launch of Warhammer Online, which is by itself, a fairly interesting point.
