Extra Channels on Bnet?

[Munkay]

I attempted to take a screen shot of the channel screen, but due to resolutions the image comes out nice and black with little purple and pink pixels added for pizzaz.

At the end of the ridiculously long channel screen there are four channels:

WCG Mercury
WCG Mars
WCG Venus
WCG Jupiter

Any attempts to join are greeted with a 'restricted' reply.

What are these? Am I missing something? Are these WoW related?
