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.
Overall, if you're a numbers fan, they've certainly served up some interesting observations based on their member statistics. Definitely worth checking out if you're curious about how things are trending for Blizzard's MMO behemoth.
