The 358th episode, which will be entitled to colour pages, is scheduled for April 26 in Young Animal #09/10. It is a double issue (but there is no double episode) because there is the Golden Week. The 11th issue is scheduled for May 24.
It at least means we'll be getting a Griffith POV episode, I was worried we'd be transitioning back to Guts too soon. I want to learn more about Griffiths evil plan.It's the usual teaser: "What will happen to Griffith and the Band of the Falcon in the capital city?!"
However please keep in mind these usually don't mean much.
