This youtube video looks promising: http://www.youtube.com/watch?v=aehDqpbN3dY , however we have no further information yet.
So as a summary:
- keys as available in the video above, with rgb colors would be sufficient
- free setting of each rgb key color via AutoHotkey should be possible
- should also support blinking up to a certain frequency, imagine the blinking speed of the RS7000 groovebox sequencer leds
- price range 500..700 Euros maybe
- good quality keyboard keys and switches, so not like Luxeed cheap plastic, something better
- should also have a Numpad section
Why?
I want to use such a keyboard NOT mainly for typing, which is of course also possible, but a general midi controller device, which I have built and using already, but the rgb color feedback on each key is missing, where I would wish I had already, so I am waiting still for such programmable rgb led keyboards to appear on the market.
Maybe the poll results can give a feel how long I still have to wait for such a product.

Thanks in advance for your comments on this topic.
