: Maybe Joe got tired of hearing the awful squeak-toy voices of the Grunts in
: Halo 4 so he is lending his voice for the Grunts in Halo 5 until he finds
: his new creative opportunity?

: Or finally, maybe 343 realized that they need serious help to clean up and
: repair the Halo universe so they hired Joe and fired their writing staff?

You know, as much as I'd love to see Joe at 343 (hah), I honestly don't know if he'd be the saviour of the Halo franchise. I think he'd bring back a lot of the style and love for the Halo storytelling, but I think his focus was more on video games (or single stories) than a large cohesive universe. The games weren't perfect remember. Bungie made mistakes, there were retcons, and they voiced their lack of interest in novels and extended fiction and whatnot, iirc...

Not that it's going to happen, but if Joe were back at 343, I would hope it's for getting back to the roots of what made Halo great, great story, and more teamwork with the people working on the larger universe, to make better self-contained video games that make sense within the grander Haloverse. Don't ignore the storyworld for the sake of a video game - but please still make an awesome video game!

Now realistically, wherever Joe goes, all the best to him :)
