The Initiative, what’s their current employee count? I heard less then 100 but I assume they can staff up on temp workers when they have a concrete plan in place. But even with 100 people you can make a AAA game if you have enough time. 4 years at least I’d say (it’s been almost 2 now I think)
47 devs I believe. They've been staffing up slow, mainly hiring top notch devs. Rumor is that some of Microsoft's other 1st party studios have been assisting them with development gruntwork since they're not filling entry level positions yet, only senior and lead positions. I could see the game being ready by late 2021 or early 2022 possibly.
