Nah, devs can just work for someone else. Wouldn't be surprised if atv gets bought out by another publisher or a tech company.
Also, cod has been nearing done for a few years now because every game came out at launch were steps down from the best games' launches and gaming years. I figure the workplace environment has a lot to do with that because ever since the infinity Ward fiasco back in the day, all cod devs' support have been hella lacking and the only work put forth has been towards microtransactions.
Nobody who makes the game actually loves what they're doing because a portion of their mind is always occupied by things going on behind the scenes
