All the talent they had went elsewhere a long time ago, which was made abundantly clear with the release of Diablo 3 and everything since.
Firstly, your prediction is conjecture and there is no evidence. Secondly, those kids or "little once" as you call them can at least construct a readable sentence.
COD games come out on a yearly basis and Activision tries to pimp every penny out of them before they reach a quick death. Overwatch has been in development (as Titan) for many years and has likely cost Blizzard a ridiculous amount of money to develop. I doubt they will prematurely kill their game for a few quick bucks since they don't have "Overwatch 18: Now With a Few New Maps" on the backburner. The only way I'd see them doing that is if the game flops, they can't fix it, and it doesn't make sense for them to keep working on it - then they may go P2W as a last resort.
