It was the most stylish video game teaser I'd seen in forever, but it instantly seemed a bad sign that they took the time to create an ARG with essentially zero payoff and no hint of when there would be an update on progress.
IGN:
According to multiple sources familiar with the matter, Bungie is in the midst of shifting around its creative leadership on Marathon, including removing long-time Bungie designer Christopher Barrett from the game director role
...
Within the company, there is a growing expectation that senior company leadership will leave in droves in the summer of 2026 when the final payouts from Sony's acquisition of the company take effect. With this in mind, there is a strong push to get Marathon out the door before then, and let whoever takes the reins after that (be it Sony or Bungie) worry about how it's sustained.
Anyway, still some extra details in there for anyone interested. Kinda wild it took reporting for them to acknowledge it publicly. It's been nine months!
