User blog comment:SonicFan/Ben 10: Omniverse on hiatus/@comment-4848837-20130406171827

Like usual, they probably won't return till sometime in the Fall or Winter (probably late August but as late as October). But this definitely hasn't been a short run. Omniverse has progressed 30 episodes, and this took 28 straight weeks.

By the way, August 1 shouldn't count as a hiatus. That was meant to be a sneak peek, not the actual premiere. It was supposed to hype viewers and get them ready for the premiere (September 22 or so).
