My bad. Should of said leaker said project mew ends next episode. He is a pretty prominent leaker but that's not confirmation etc.
But based on the preview and how they are battling mew, looks like the end to me. But yeah, wait and see
Reminder that catching Mew isn't the end of the arc
Even if it's in Goh's possession for a few episodes there are still villainous forces coming down on it
