The Lionhead website has a curious update to it today. The above image of Che Guevara has cropped up on a splash page with a "6" next to him. The thumbs below determine a skin on the main site when you click on them, red for a positive response and blue for a negative one. But that's all it seems to do and there's no further information on the site relating to it.
With Gamescom coming up next week and the suggestion that there's going to be a "special announcement" from Peter Molyneux, it's probably a good bet that the teaser relates to it in some way. Could the infamous teller of development tall tales be planning to incite a revolution at the event? We'll be keeping an eye out for any further developments as they arrive.
