DirectX 10.1 runs on DX10 hardware
Here's a follow-up on the story of a couple of days ago saying that DirectX 10 hardware would become obsolete when 10.1 arrived. Microsoft now denied that statement.
The changes "aren't that critical", so it is rather unlikely that applications specifically for 10.1 will be built any time soon. It's just a way to increase the API life cycle.
Contemporary graphics accelerators from Nvidia GeForce 8800 and AMD/ATI Radeon 2900 may not support all the new features added to Direct3D 10.1. The features of DirectX 10.1 include incremental improvements to 3D rendering quality. As for the innovations, among them are 32-bit floating-point operations (instead of 16-bit ones, used today by default) and obligatory support of 4x FSAA.
Microsoft's Sam Glassenberg did however note that "DirectX 10.1 fully supports DirectX 10 hardware. No hardware support is being removed. It's strictly a superset. It's basically an update to DirectX 10 that extends the hardware functionality slightly."

M$ has clearly been taking a lot of flag when releasing such a "follow up", and rightly so!

"DirectX 10.1 fully supports DirectX 10 hardware. No hardware support is being removed."
I dont think anyone raised the issue of DX10.1 comming out that DX9 and more specificly DX10 cards not working anymore , DX has as far as i know always been backwards compatible , aka with windows vista and DX10 installed , you can still play DX9 games on your DX9 card .
The issue that was raised that if DX10.1 is released together with DX10.1 games , that DX10 cards would not be able to show all the new features ( i dont know whats new so i just assume ) as for example DX9c games requiring SM3 while DX9b requires SM2 , a x800xt for example cant play Bioshock in DX9mode even though the card is fully DX9 compatible (duh) but the lack of the "small" SM3 compatibilaty .
so ppl with a 8xxx or 2xxx card are worried since they spend alot of money on a DX10 only to realize they might have to get another upgrade sooner then expected , hopefully someone can shine some more light on it
