It is interesting. I just got a mail from the maker of Coppercube:

This engine can also create 3d flash games and already has a working demo that runs on the beta flash player with 3d hardware support.

I also wonder how the Unity guys can embrace new platforms so fast. It is crazy how they are always faster than the big guys.

In the end I see it exactly the same like Kiyaku: More users means more clients means more success for us service providers. Thank you Unity!
