Rag was right about one thing though...
Hard to be interested in something you've never heard about :P
Was i?

I never heared about Star Wars: Knights of the Old Republic III. being in development ... and im very interested in it.

Yes you were Rag. You can't be interested in the development of a game if you don't know that the development is happening. You can though, be interested of learning that it is happening or will happen in the future, i.e. hoping to hear/read/get news about it. It's a small difference in definitions but it's there.
