The apostle John was said by many to have been translated by the Lord, as Enoch and Elijah were:
Then Peter, turning about, seeth the disciple whom Jesus loved following; which also leaned on his breast at supper, and said, Lord, which is he that betrayeth thee? Peter seeing him saith to Jesus, Lord, and what shall this man do? Jesus saith unto him, If I will that he tarry till I come, what is that to thee? follow thou me. Then went this saying abroad among the brethren, that that disciple should not die: yet Jesus said not unto him, He shall not die; but, If I will that he tarry till I come, what is that to thee? This is the disciple which testifieth of these things, and wrote these things: and we know that his testimony is true.
John 20:20-24
People who are translated don't skip the dying process; it just happens that they are changed from flesh and bone to a translated state, then are resurrected in the twinkling of an eye.
If true, then yes, John remained. We know that Jesus died in 33 A.D., yet John's Apocalypse was written circa 100 A.D. There was a legend that the Romans tried to kill him by dropping him into a vat of boiling oil, but that he emerged from it unharmed. He was then exiled to the island of Patmos, where he lived many years before vanishing shortly after the Apocalypse was written.
It's rumored that he's now living in Brooklyn under an assumed name and is a member of the Governing Body of Jehovah's Witnesses. He's in charge of establishing new dates for Armageddon and subsequent articles for why the dates didn't pan out.
