Atlantic Records has released a producer list for "Press Play":

When Bad Boy founder and CEO Diddy decided to return to the recording studio for his first solo project in five years, he also decided to recruit an A-list team of cutting-edge producers to turn his widescreen vision into a musical reality. With Diddy himself serving as both executive producer and hands-on producer for much of PRESS PLAY, he collaborated with a crew of studio innovators to capture the spectrum of sounds and styles that he wanted the album to embody and reflect.

Joining Diddy behind the board were such production aces as Kanye West, Timbaland, Just Blaze, the Neptunes, Havoc from Mobb Deep, Mario Winans, Will.I.Am from the Black Eyed Peas, Rich Harrison, Danja, Big Boi, Rob Lewis, J-Dub, K-Def, Grind Music, and Jai.
