for eu, you can forget NA engines for small cars. i think the ford Ka+ is still with some old 1.2L NA, but fiestas class and above will be with turbo and with active cylinder shutoff.
right now trend towards electrification, lots of mHEVs, pHEVs and FHEVs coming out next year.

for low cost countries and where emissions law is not a factor, the NA engines will be pushed there as long as it is still profitable as its much cheaper, old tech and has been value optimized.
