Dr. Halsey, Spartan II's & III's in H4?

I just finished watching the GameCentre exclusive interview with the illustrious Mr. O’Connor and although it been established that there will be other Spartan’s, particularly the new Spartan IV’s I’m curious if we’ll see any of the surviving Spartan II’s, Spartan III’s, Dr. Halsey or CPO Mendez?

Now it’s been awhile since I’ve immersed myself in the Haloverse but if I’m not mistaken the surviving Spartan II’s are Fred-104, Linda-058 and Kelly-087. Jerome-092, Alice-130, Douglas-042 are persumed MIA on the Spirit of Fire and Adriana-111, Mike-??? and Jai-006 are to far behind enemy lines to be contacted but are presumed still alive.

As for Spartan III’s it’s Ash-G099, Olivia-???, Mark-???, Tom-B292 and Lucy-B091.

Do you think we’ll see them in Halo 4? Better yet would you even want them in Halo 4?
