It’s been officially announced by FUNimation Entertainment that they will start doing English dubs of Dragon Ball Super in the very near future. My guess for the release of English dubbed episodes would have to be sometime during the summer or fall of 2017.
As of right now, FUNimation has a multi-year agreement with Toei Animation to bring digital downloads, streaming, and video distribution of Dragon Ball Super in the United States and Canada. Episodes 1-10 and 47-64 with English subtitles are now available on FunimationNow streaming service.
YouTube and other popular video websites are flooded with Dragon Ball Super videos, no wonder why FUNimation is finally pulling the trigger to officially release these episodes in the United States and Canada. Dragon Ball continues to be an exciting worldwide phenomenon.
