Why would you then trust the thing you posted, which seem nothing more than a blog?
Anyway, what it just looks like to me is that DX10 and 11 do bring new features, but that they've been for the most part announced early, and handled as if they were already there. That is true especially for DX10, and the features are actually there in DX11.
The other problem that DX faces is that the difference really isn't that big between DX9 and DX11. Partly because developers in general can't be bothered to develop a game that will not reach half of the gamer's population, but also simply because the visual difference is not as big as advertised.
OpenGL to me is the sad story. The one of the product that has actually got more potential than its competitor, but which cannot do much because it is plagued by delays, questionable management and weight of the giant, dominant product.
Now, getting OpenGL to LFS probably will not happen. They're quite different APIs and while I'm not very well versed in programing, I'll assume that making the switch is impossible without designing a whole new engine.
