Yes, 3.7.1 will also work as it isn't a major update release. Its just some bug fixes and a critical security update.
Since our templates run on a framework all future versions of Joomla will work too. We say this because if there perhaps is an issue we can just update the core framework files and release a new Vertex patch that can be applied to all templates. We don't have any code that is specific to Joomla in the actual template outside of the Vertex core.
