The Nintendo 64 classic Banjo-Tooie is set to be released on the Xbox Live Arcade later this month, and with it Rare will be releasing a new premium theme. New themes are released each week, but this one has sent the Internet into a bit of a spin, as the Perfect Dark icon can clearly be seen in one of the screen shots.
A Joanna Dark icon can be seen in the 'Latest Games' section of the 360 menu. It's important to note that this is the Joanna Dark from the original Nintendo 64 Perfect Dark, not the one seen in the 360's Perfect Dark Zero, suggesting the N64 hit title will soon make it's way to the Xbox Live Arcade.
As you would expect Rare and Microsoft have refused to comment at this time.
