Multicast was also required for earlier versions of VXLAN.  But later versions or VXLAN only require unicast.

For the far future it seems like Named Data Neworking, Content Centric Networking, Information Centric Networking, Data Centric Networking etc all list multicast as a requirement or fundamental part of their architecture.
