But when they introduce fermi i think we will see more dx 11 games because Nvidia does have far superior marketing than ATI
I don't think NVIDIA's marketing will affect DX11 implementation since NVIDIA does not own DX11. Developers will use DX11 only if they want to. More DX11 games will come out simply because more time has elapsed. Games are still in development with DX11, some in the early stages which won't be out for another 2 years or more. It's not like when Fermi comes out a bunch of developers will start working and then bring out a title by the end of 2010. Games take 2-3 years to develop at a minimum, so all we'll see until at least 2011 is tacked-on-to-DX10 stuff.
