When will OpenCL implementations arrive?

I’ve heard OpenCL will be included in OS X 10.6 to be released sometime this summer. How about other OpenCL implementations?

AFAIK ATI, Nvidia, Apple and Tungsten Graphics are working on OpenCl implementations. Any others? Any information about dates of initial releases?


NVIDIA has already demoed their OpenCL capable driver in SIGGRAPH ASIA. They have not officially released it though.
