CUDA for Kepler?

I’ve been reading that the new GTX 680 cards featuring the NVIDIA Kepler architecture are supposed to be released very soon (apparently March 22nd, 2012), and I was wondering where and when us CUDA developers would get some more information about the architecture as it pertains to our HPC needs.

Is anyone from NVIDIA able to comment on when we can expect to see concrete details for CUDA on Kepler?

All previous major GPU releases have been accompanied by a simultaneous CUDA toolkit and driver update, as far as I can recall. It might initially be a beta release only available to registered developers, so I would suggest signing up if you have not already.
