Last week's Xbox 360 event in Sao Paolo, which teased Forza 3, also spun off another rumour tidbit. That pic, sent over to Destructoid, which is the second in-the-wild sighting of Perfect Dark on XBLA.
The image, says D'toid, comes from someone who attended the Brazilian showing and quickly snapped the image. A video of the event, showing Forza 3, was uploaded and quickly taken down.
On the ESRB, Perfect Dark remains rated only for the Nintendo 64, not XBLA.
