Ubisoft showed a level of Watch Dogs that is exclusive to PS3 and PS4 during its gamescom press conference. All told, Sony can boast 60 minutes of additional content on PS3 and PS4. There are four exclusive missions (including the one in this trailer), a new costume, and a hacking boost perk.
Ubisoft is also partnering with Sony to make "a blockbuster movie" based on Watch Dogs, the interesting Ubisoft game coming this year to every system outside of your smart fridge. According to Polygon, the film "is in development at Ubisoft Motion Pictures, with production being handled by Sony Pictures and New Regency."
I hope it's a spiritual successor to Tim Allen's The Shaggy Dog. Or the John Travolta/Robin Williams classic Old Dogs.
