Although thus far there still isn't a Batman game out to go with the new movie. Many of us geeks are willing to overlook that and still have an Xbox customized with The Dark Knight logo on it.
This one was spotted in Taiwan and is apparently an extremely limited edition version made by Microsoft. Which means it will likely be near impossible to pick one up for yourself.
Between the combination of the overabundance of fans from the recent movie and these being in short supply. Not to mention they probably want you to offer up your first born child in order to get one. Sadly, the best most of us would likely get is just a Dark Knight sticker slapped on our Xbox.
