He chose not to renew his contract, he left WWE, said he and Melina were taking a break, hes appeared for several independent promotions since he left, most notable being Family Wrestling Entertainment. He never said he was in contact with TNA, rumors said they had discussions but obviously not has came to fruition, he recently stated that he and WWE are on good terms and that he sees himself returning somewhere down the line when his batteries recharge.
I'm not even a fan of his, but I do give him credit for pinpointing his own faults. He has admitted his failure in wrestling is charisma and talking on the microphone, that he'll improve and when he returns to WWE we'll see a better version of John Morrison.
That is what has happened to John Morrison, could have easily Googled it.
