Ok so:
The question is: since we know he is alive from a developers mouth, do you think there is a possibilty for a sequel/prequel or DLC explaining Jun and what happens to him. I realise Bungie is done with Halo, but I've heard rumors of 343 studios taking over, and if that's true, is there a possibility of finding out what happened to 117 after the legendary ending in Halo 3?
As you probably know, Jun is the only member of noble team whose fate is uncertain, the last we saw of the sniper he was escorting dr. hasley off of reach. I beleive in the following credits, you could hear dr. hasley's voice, meaning they survived. According to the legendary edition developer: "Jun is alive".
