Let's just admit that Jon Jones is a real life Terminator. If Cyberdyne Systems wanted to create the best T-800 model, it would be based on Jon Jones. That's why it's more than just a snappy quote when Carlos Condit told Ariel Helwani that Jon Jones told Condit that, "He'll be back."
Whew, that was convoluted, but it doesn't make it not true. Even if this information is coming like a game of telephone, we'll at least be able to see Jon Jones back and doing his thing once again. He'll come back, he'll win the title again, and he'll be right where he left off - the best fighter who ever lived.
