At the very least, the next cycle would probably have a seriously different galactic civilization. The yahg are only a couple of centuries away from spaceflight - if the Reapers cull the current races, the yahg interstellar civilization will develop very early compared to any of the modern ones, with possibly tens of thousands of years of existence by the time the Reapers roll around again.

What we'd probably get, given their aggressiveness and intelligence, is something like the Prothean Empire, but much more advanced - clearly very different from Citadel civilization.
