3D texture Access Is it planed ?

I wonder if 3D texture access (with tri- and quadri-linear filtering) under CUDA is planed for future releases of CUDA since only 2D textures seems to be currently supported under CUDA 1.0.
I noticed that the PTX assembly expose this feature, is it currently implemented and usable ?

Thank you in advance !

Up !

Yes, they are planning to implement these
