I'm not an Xbox gamer but my bet is PC. Even with Xbox still supporting consoles, the weak Xbox Series XS aren't translating to PS5 outpacing PS4, and we know that PC is the fastest growing platform. So Xbox players may already be slightly contributing to PC's growth (although the biggest contributor by far would be the rise of China).
Xbox hardware is also not exactly exiting, rather it's transforming to PC gear. This alongside MS having a PC store and programs like "Play Anywhere" and "PC GamePass" should help with the jump to PC.
