You have a point, but Overwatch is still a new franchise, and for me it resurrected online FPS gameplay which hadn't changed much since I played TFC and Counterstrike nearly 20 years ago. I'd expect them to dedicate a substantial portion of their efforts towards maintaining and growing that franchise, and would for at least the next few years would consider that investment towards the "new".
