Well i switched to the 360 from ps2, Then to the ps4 from the 360. Doesn't matter how powerful it will be, I'm not switching back again, Just to play Halo 7 or Gears 5. They need new games that appeal to me, Not a new console that has a better chance to run Multi-plat games better.
Also i get all games( new/old ) half price on PSN( primary account trick me and my bro use)
pretty sure you could do that "trick" on Xbox one too
