Yep, a new episode is airing in Southeast Asia.

Steven Universe S05E05 - Dewey Wins
HK Airdate: August 25th, 2017 at 5PM GMT+8
Synopsis: Steven helps Mayor Dewey run a difficult campaign.
NOTE: Listed as S05E05, but could be based off production codes.
NOTE 2: I have a stream (720x576p 1.2Mb/s + 64Kbps mp3) to cap it.
I’ll try if I can find a better one.
