"We found out that Microsoft plans to finish up DirectX 11 in late 2008 or early 2009. This means that it will move rather quickly from DirectX 10 and 10.1, but it might take some time for hardware to go the same way.
We still don't know many things about the new API, but at least we have the rough plan that it is coming. It is clear that 2009 will be the year of DirectX 11, and the way the market works we should see some good DirectX 11 games by 2010.
Seems like an eternity now, but as you might know, tempus fugit."
