Microsoft made a presentation at SIGGRAPH 2007 indicating that
DirectX 10.1 requires new hardware.

Does anybody know why the few changes in DirectX 10.1 rendered the
10.0 hardware obsolete just 6 months after Vista was released?

Couldn't DX10 hardware that already supports the additional features of DX10.1 be compatible? Sounds to me that it is possible. Perhaps all the low-end cards would not be DX10.1 compatible, but the high-end cards might be. Although I haven't looked at the spec of any DX10 cards to know for sure.
