dx11-compatible graphic plugin?

Well ... According to Microsoft, DirectX 11 should be a perpendicular support/upgrade, which means all DX10 compatible cards will be available to use DX11, regardless on NV or ATI cards.

I don't think so. DX11 has exclusive features that can't be done with DX10 hardware, one of them being tessellation.

yeah it has some features which need a DX 11 card but it works perfectly fine with DX10 cards when you use direct compute (you integrate different levels so the use of DX10 is sufficient) also the multi threading features of DX 11 do work with DX 10 cards without problems

so the only big change with DX 11 that can't be done on a DX 10 card is tessellation... which (most likely) won't be used in GSDX
how about you inform your selves before you shoot some ideas in the wind -.-

(and for the record that direct Computing is usable with DX10 cards doesn't mean there is no gain in using a DX11 card for it)

The Direct3D 11 runtime will be able to run on Direct3D 9 and 10.x-class hardware and drivers,[14] using the D3D10_FEATURE_LEVEL1 functionality first introduced in Direct3D 10.1 runtime.[13] This will allow developers to unify the rendering pipeline and make use of API improvements such as better resource management and multithreading even on entry-level cards, though advanced features such as new shader models and rendering stages will only be exposed on up-level hardware
