Well, I think it already kind of is. If you've been paying attention to 343i since Halo Infinite's release, you'd have seen a pretty steady exodus from the studio. The individual in a Senior position, responsible for the atrocious progression systems, exited the company, for example. They took a small number of 343i's employees with them, and setup shop making mobile games. Their CTO was also recently replaced by an old-guard Halo developer and Bungie vet, which should help immensely.
Looking over the last year or so, after the disastrous Halo Infinite Gameplay reveal, Joseph Staten joined the team, and he has quickly become the face of 343i. Staten has been Microsoft's fixer for a while, and I'm betting he got a fancy big cheque to get Halo back in line. Bonnie Ross is MIA, Kiki Wolfkill is off in TV land, and Frank O'Connor seems to have disappeared into another dimension. This is what happens in corpo land when you've royally fucked up. Forcing the Xbox Series X|S to launch without a game, and forcing Microsoft to pay for all those timed marketing deals they'd already invested in? And then launching the worst live service since Anthem, one that's performing so badly that they're forced to add microtransactions into eight year old games to make up the missing revenue? Yeah, that's about as big a fuck up as you can get in this space. In these scenarios, you're not fired - you simply fade into the background, before you're allowed to graciously "move on to new exciting projects".
All's quiet on the outside, but inside, I'm betting 343i is a killing floor. Hopefully the company that emerges is that much leaner and hungry to earn back the goodwill that 343i burned.
