PC rumors suggest Halo 3 and 4 may arrive for PC.
It seems the excitement around buying Xbox consoles for Halo 5 hasn't matched that of previous titles like Halo 3. The games aren't as popular now, making it less likely people would prioritize a console just for that series.
They only need to purchase the Xbox if they wish to play Halo 5, making it a necessity for their console. Transferring it to PC would likely hurt Xbox sales significantly. The majority of purchases would go to PC, so those who buy the system solely for Halo wouldn't require it anymore. Racing games and Halo together form a strong Xbox experience.
I'm not aware of any friends who play on Xbox and own their console for racing titles or Halo. They just upgraded from the 360 and preferred something familiar, so they switched to the X1. In reality, I believe I purchased my X1 mainly for NHL 15, Destiny, and because those games were popular among my friends. Still, I concur with your thoughts that Microsoft likely won't release Halo for PC anytime soon. The Xbox's future seems tied more to the X1 and Forza than to its gaming library. I've heard many people buy the Xbox over PS4 just because of the X1 controller, not because of any specific games.
