In an interview with EDGE magazine, President of Sony's Worldwide Studios for Sony Computer Entertainment Inc, Shuhei Yoshida revealed why PS4 title Knack was revealed first. Yoshida revealed it was a gesture to Mark Cerny who heading Knack's development. Revealing Knack as the first title was due to a desire to establish the PS4's aim in offering a range of varying experiences. Most telling of all was his remark of " We were like yeah we hate to see all the PS4 games being FPS or action-adventure or very photorealistic."
Considering Sony's recent stealing recruitment of Indie developers, it seems Sony seem to have a cohesive vision in what they want to the PS4. Sony truly are worse than the Mafia.
