The lights are on
Watch Dogs was one of the most buzzed-about reveals from E3 last summer, and many were speculating that it would be a next-gen title. Kotaku has received some leaked marketing material for the game, and they might contain a hint regarding the game's availability.
Instead of the standard "Available for Xbox 360 and Playstation 3" line, one poster lists the game as "available on all home consoles." It's vague, but could possibly hint at something we've been speculating about for months.
One of the pieces of marketing features a quote from G4 stating that Watch Dogs is a "truly next-gen adventure." So basically, don't be surprised when you see Ubisoft's new IP on the next generation of consoles.
