Graphics Rewrite and navigation?

Has Luthier said anything about Direct X 11 support? He said that it was a high priority before the game was released, and has yet to comment on it. You'd think with a new graphics engine it would go without saying that DX11 is supported, but saying it would be nice. I've heard that some games run faster with DX11 than 10, and it would be nice if the new graphics engine didn't just give us the fabled 50% fps increase, but some due to DX11 as well.
