There is no way I can given a specific time to support 3.0, since it's not finalised nor any implementations available. I can say that I'm a committed supporter of OpenGL in general and the path the ARB are taking to OpenGL 3.0, so I'm following developments closely with the intention of supporting it. There are some major technical issues to resolve w.r.t how we go about integration. In some ways a clean slate, OSG 3.0 mapping to OGL 3.0 would be ideal, with the both general hardware, OSG and OGL all becoming ever more multi-threaded, and with new object models that perhaps suit a different means of encapsulation at the scene graph end. With a clean slate OSG 3.0/OGL3.0 would be trim down the scene graph substantially too. Perhaps also an opportunity to improve the scriptability of the scene graph too. A clean slate approach is not good for existing users, not good for getting out version of the OSG with OGL3.0 in a timely manner. Right now we need to support the latest OGL extensions, then look at how one might integrate OGL3.0 features in a relative non intrusive way. The OSG has already coped surprisingly with evolution from OGL1.1 to OGL2.1, so we can probably handle OGL3.0 too given a willingness to refactor parts that need it. Maintaining backwards compatibility with older versions of OGL is what will complicate things, I see its part of the OSG's role to hide this complexity of managing multiple OGL versions so I'd like to see a graceful way of handling the new object model.
