Real Talk... Mark VI Gen-III in PvP... yes or no?

Halo 4 and Halo 5 really irked a lot of players with the fact that they could no longer dress up as MCPO John-S117 since his new redesigned armor, the Mark VI MOD, was unavailable for use in multiplayer for some reason or another.

So, will we actually be able to use the Mark VI Gen-3 armor John wears in Infinite in PvP as an unlock? I presume it will be only available for players who beat the game on Legendary or something.
