It says that Unity supports the Wii engine, but a Wii devkit is only available to developers how can we support unity on the wii?
You have to buy the Wii license from Unity. From what I’ve heard it runs at about $7000-$8000 (available upon request).
To develop on the Wii you have to be a certified Nintendo developer. Once you are, you can talk to Unity about licencing the tech.
In other words, Unity Wii development isn’t homebrew. It’s for funded game developers commiting significant capital to their project.
Is it going to be the same for the PS3 thing coming out soon for Unity 3.
Very similar.
