For the week ending December 11, Chart-Track's UK All Formats chart had Call of Duty: Black Ops at the top, FIFA 11 in second and the highly anticipated expansion, World of Warcraft: Cataclysm, in third. Yes, that math feels all kinds of wrong. Here's a perfect example of how the lack of online sales tracking can create an issue when looking at Chart-Track and NPD results. Cataclysm was the first WoW expansion, a game that reportedly has 12 million subscribers, to be available both at retail and online. It seems that unless players were interested in baubles, they were more than happy to just pay Activision-Blizzard for the authorization key directly online.

In other news, it looks like the UK caught on that Disney Epic Mickey launched. The Wii exclusive, created by Warren Spector's Junction Point Studio, finally broke into the Top 40 at 37, "misunderstood" design and all.

And because it's our obsessive fascination, we'll tell you that Just Dance 2 slipped a mere single spot into sixth. That means we are only a few weeks away from a member of the Just Dance franchise holding a place in the top ten for nearly all of 2010. Check out the UK's top performing titles after the break.
