You're right about that, but you need to consider development time. DX11 will lag behind DX10.1 development as there are already games in development that use DX10.1 technology.
ATI is already set to go with the Tesselator for DX10.1 implementation in a future driver set. Frobles, a demo utilizing the technology, will be released alongside it within the next driver or two according to Eric Demers in a recent interview over on Rage.
