Speaking to Joystiq, Guay confirmed that the E3 demo is running on PC, but emphasized that Ubisoft Montreal is interested in getting Watch Dogs on "all the platforms we can." That means Xbox 360 and PlayStation 3 versions "for sure," Guay said. A Wii U version is still up in the air.
It's easy to imagine Ubisoft releasing a scaled-down, optimized version of Watch Dogs, positioned to take advantage of the large, established audience on current consoles. It's even easier to envision the futuristic property popping up in Ubisoft's typical barrage of launch games for a new system. Both scenarios could play out by the time Watch Dogs ships, sometime after 2012.
