Banjo & Kazooie spotted on Xbox version of Sonic & Sega All-Stars Racing

One of these box arts is not like the others. Yep, you'll notice that the Xbox 360 version of Sonic & Sega All-Stars Racing has two added bonuses: Banjo and Kazooie. At first, we were quick to dismiss the image as nothing more than a fan mock-up. However, TSSZ discovered that all of these box arts can be seen on Sega's server (Xbox 360, PS3 and Wii).

If the addition of Banjo and Kazooie to Sega's kart racer sounds familiar, it's because it was part of a Sega leak earlier this year that contemplated this exact partnership. Revisiting the supposedly leaked Sega document reveals a number of bullet points that have already come true: the PS3 price drop, Alpha Protocol's delay and Yakuza's localization. The addition of Banjo & Kazooie to the Sonic racer is a nice bonus; however, should other aspects of the Sega document come true, it could mean PS2 and Dreamcast games are coming to PSN.
