Tony Parisi, one of the co-creators of VRML--Virtual Reality Modeling Language--along side Mark Pescue, recently discussed the future of Virtual Worlds. When asked "What conditions should be present that are not today for a serious widespread of virtual worlds in the future?" Tony response was "two things. First, a ubiquitous client. Either Unity, or a Unity competitor; or WebGL (maybe not version 1.0 because it might not have all the features)." The second item is game play within the virtual worlds.
