From the rumors they may be re-introducing the MW series to next gen at the end of the year. If so then everyone can take a chill pill and have a choice to play old-school simplistic style or play the new options-galore games (Ghosts - AW).
I will be pretty happy with that (in theory), the biggest problem with Ghosts on PS4 is that there isn't a fallback, so people want Ghosts to accommodate every damn aspect, which it cannot and never will be able to.
End of the day the community is like greed, never sated and ever demanding.
