Play Like Batman with Batarang Controllers

I saw a picture of the Xbox 360 version of the Batarang Controller on the internet and so did a little search to find a post on Geeks of Doom which feature a few images.
For some reason, the Xbox 360 controller is wired, seems a bit strange unless it was to keep costs down, but anyway, they were unveiled well before E3 from a company calling themselves POWER A.


The controllers are due for release at the same time Batman: Arkham City on October 18th, not sure about in the UK though.
