UPDATE:Amazon has removed the screenshot from the page. Did the retailer jump the gun on something SEGA weren’t ready to reveal yet? /UPDATE END

Amazon’s Japanese website has posted a new Sonic Colours screenshot on the game’s product page there, which reveals a co-op mode. In the screen. we see two Sonics, one blue and one pink (or red?). Two separate HUDs can also be seen on the left and right of the screenshot with no split down the middle, suggesting that this is indeed a co-op mode. What’s  odd about this picture is the environment. For a game titled ‘Sonic Colours’, there sure isn’t much colour in this stage.  Also odd are the antennas that both Sonics have on their heads. Could we be seeing Sonic robots, like the Shadow robots in Shadow the Hedgehog’s multiplayer modes?

What do you think about this interesting development? Speak out in the comments.

Thanks to Hero of Legend at the SSMB for the find!
