Josephson junction arrays have become an archtype in the study of mutual synchronization of coupled oscillators. After briefly recapping some recent theoretical progress, I'll turn to open problems and future prospects for these superconducting systems. These new directions include the role of disorder, modulated spatial patterns, and even intermittent avalanching dynamics which manifests itself experimentally in magnetic flux creep. I'll also discuss how progress on Josephson arrays may help us tackle other systems of interest in applied physics, specifically laser arrays and quasioptical semiconductor arrays.
