double precision will be double precision available soon?

Hi,

I made a working prototype of molecular dynamics simulator using CUDA technology.
The next step is an introducing it into the real product. Unfortunately floating arithmetic make development too tricky. At the last year was information that double precision will be available soon.

Is there some information about the time it come? Should I develop relaying on current technology or wait for a short time when double precision come?

If you scroll down a bit…
