I have heard some things about Gnomebuntu which is to be a new Ubuntu variant, although that may not be its final name. There is an article at world of gnome, which describes it as a community developed variant (much like Xubuntu), but will it be classed as an official variant like Xubuntu? I wonder if anyone else had any more information on the project?
Thanks izx, we might as well leave the question open so people can add more information as the project develops.
