DX10 was not a failure, not by a long shot.
Unfortunately people don't understand a API is exactly that, it's not an application,l tech demo or game. It's an API. At the time of release DX10 was the best real time graphics API available and DX11 builds on that. MS stated many times that DX10 added flexibility and speed more than anything else. Integration vs specialization (DX9 and lower)
the tool will once again be the most advanced available, whether developers take advantage of it or not is an entirely separate issue.
