Lyoto Machida is going to be champion again at light-heavyweight, but it's going to be after Jon Jones move up to heavyweight. I think Jon Jones will take on Alexander Gustafsson next for the title, because that's who he is gunning for next. Jones wants Gustafsson to prove to people that it's not just his length that allows to win fights. I'm not sure why he wants to do that, because those people are probably a little retarded anyways.
Nonetheless, expect Jones to dispatch of Gustafsson, and that would break the record for most title defenses at 205 with six and surpasses Tito Ortiz's record. And Jones' work is done at 205. Next for Jones would be a superfight with Anderson Silva, and then from there he will move up and take a "tune up" fight at heavyweight, and work to capture the heavyweight gold.
And at 205 the second best fighter in the division will become champion: Lyoto Machida.
