Well he did just create the Tekunin, but didn't accomplish anything.

I think there's a very strong possibility. He's got more chance than Smoke, put it that way. Sonya is pretty heavily rumoured to get in, and right now, he seems like the best antagonist for her to try and bring down.

I honestly think he should survive, but in my personal opinion, not actually appear. If his Tekunin story is going to be where they go with him (which is the only reason I can see them bringing him back), then it seems more fitting that he would actually send minions in to do his bidding. Why put himself in harm's way himself? Tekunin leader Sektor in MK8 actually seems more like a metaphor to me than a realistic outcome. Unless there is some reason Sektor personally feels the need to fight.

Anyway, right now, no one knows anything. He's not a character certain to return, but he's got a very good chance compared to many others. He probably makes the top quarter.

Yes, Sektor could return, but equally no.

It depends on whether MK8 is retconning the entire series or not.

I say 70% yes and 30% no.

not because im a fan, but because they just braught in the Tekunin. That was probebly one of the things out of mka that made for good plot possabilities. it would be foolish.

Sektor will return, if not, they better give him a good death, not get owned. and i want to see him kill somebody before he goes.

I was just thinking, unlike organic beings, Sektor potentially has no limitations, he could modify himself until he's in Megatron's league.
Is there any way people could see him as the boss, or a sub-boss in the next game?

There could be a possibility, but as Sub-Boss only. But that would be stupid, because we wouldn't be able to play as him. Yes, the Main Boss and Sub-Boss should not be playable at all.
