Halo 5 Guardians Possible Main Character (Thorne)?

So yes the main character of Halo 5 is of course: Master Chief and the newcomer Agent Locke

But i was on a website IMDB and it tells us the people who will be voiced in Halo 5

Now one character impiticular in this Gabriel Thorne(Main character from Halo 4 Spartan Ops)
Last we saw him he was mourning over the death of his family after the Didact evaporated most people in New Phoenix. He was also wanting to know what it takes to be a true spartan.I really grew on the character after going on spartan ops and reading the Halo comics.

So my question 343i and fellow Halo fans:

Will we see Gabriel Thorne in Halo 5 Guardians.-along side Agent Locke and his crew?(If u saw in Final Halo 2 Anniversary cutscene Agent Locke is standing alongside several other spartans thus his crew)

I hope so, I ended up liking him alot.
