As i see it OpenCL would only make slowing down development on Octane at this point. Also consider that OpenCL isn't in phase that you can say its mature and you can use it for everyday use without too much problems. At this point Octane is still in dev phase so when it gets to mature state and solid core, then maybe they'll think about trying to make OpenCL equivalent, but until then Octane is still in state of changes and adding new things, wich usually takes some "tweaking" in things thats already there or actually recoding them to work with new features. So imagine how much work that will take to dev for both Cuda and OpenCL wich uses diffrent approaches to get the same thing on both or to act equally. Not to mention optimizations wich are usually always the hardest part to get the same speed or atleast approx. of same speed on both and most important - visual results wich need to be the same.
thats why i don't see any use for OpenCL equivalent at the moment.
Open CL on the roadmap? When?

Man this all has become heated to some degree. Like it was said before, I don't think OpenCL is strictly off the table, just not right now. Its still cooking away in the kitchen. Or more like still in the fridge. I really see the benefits of OpenCL. I'd love to buy ATi cards which are a lot cheaper per core/gflop. I just look at it like AMD vs. Intel. Yeah AMD is cheaper and theoretically can do more quicker, but Intel has the market share, and probably will for a long time. I use to be a huge AMD fan boy, but after seeing better performance in rendering from my core2duo vs. my phenom 2 x4, I have to say I've switched over. I was the same way with ATI vs. Nvidia for a long time. I'm on a tangent.
Even CUDA is still in frequent update mode. How many CUDA releases have we seen in the last few months? It is easier to develop though when the engine is a little more established and stable. OpenCL still has a little time to go to get there. Maybe in a year's time we will see a lot more from their camp and things might swing their way.

Hi guys,
Given the numerous issues, bugs, unpredictable behaviour, changing architectures, new cuda toolkits that create massive driver problems, etc...
Imagine what this place would look like if we took on OpenCL.
