As nothing had been done for the next issue when it all closed down they need to find an editor, a graphic designer + ? then write bits a put a magazine together before sending it off to printers & distributing it. I would think that will all take at least 6 weeks - & that assumes that they have an editor, articles stored etc. End of July sounds possible (just).
I would also think that they need to be sure of content for the 2nd issue before telling everyone that it is all go. Remember that there are not going to be many event reports to fill pages.
