The Belgian arm of the EA website has let slip the first DLC for Crysis 3. It's all in French, but I took that at highs chool so let me translate for you.

"Take your nanosuit to the next level. During a much needed holiday after fighting the resurrected soul of Raptor Jesus, Laurence 'Prophet' Brown faces his greatest challenge yet. Beach volleyball against the Ceph! Only his superhuman reflexes and rigorous training can help him do something even greater than save the world!"

That's verbatim by the way. French is a very wordy language.
