I highly doubt we will ever see other Spartan Generation II’s in Spartan Ops, since most of them are supposed to have died when the Covenant glassed Reach. I don’t know what you mean by “MC” other than “Marine Corps”… but we already see them in Campaign and Spartan Ops. Care to elaborate?

There are still a handful of Spartan IIs still alive, most of them being the members of Blue Team, as well as Naomi and possibly Grey Team.
And by “MC”, he means “Master Chief”. You know, the main protagonist of the Halo games? 
There are three Spartan-II’s, Linda, Kelly, and Fred, stuck in the Micro Dyson Sphere at Onyx.
There are also three Spartan-II’s, designated “Gray Team”, were said to have been on “fields of battle too distant to be easily recalled.”
Of the Spartan-III’s (Gamma Company), there are two teams that remain. There is team Katana that is stuck in the Forerunner equivalents to cryo-tubes.
Team Saber is the other remaining team. The team consists of Ash, Holly, Dante, Olivia and Mark. Of them, only Ash, Olivia and Mark are alive in the Dyson Sphere.
There are also two Spartan-III’s (Beta Company) remaining, Tom and Lucy.
So, all together there are 7 remaining Spartan-II’s and 10 Spartan-III’s.

Tom and Lucy were in the Dyson Sphere as well.
But they were all rescued during the events of the novel Glasslands.

And the three Spartans from Red Team on board the Spirit of Fire.
Point is: MC is alive and there are SIIs and SIIIs that could be having cameo apperances.
