While we are still waiting for Unigine Corp (or their partners) to actually release a game based upon the Unigine Engine (Primal Carnage backed out and so their own OilRush game should be the first when it ships this quarter or next), the advanced multi-platform engine continues marching forward. The Unigine Engine already supports OpenGL 3/4 and has amazing graphics as shown by their tech demos like Unigine Heaven and many other features, but they have just made another huge update to this Linux-friendly game engine.
