Why Notorius Games not into Team expansion and investments?

That would speed up the development dramatically and will allow to attract more players.
I'm following this game for a few months now, nothing has changed really. People are asking the same questions on the forums that I did.

This project is the leader in sandbox MMO and can kick *ss to other indie sandbox games out there, but with only 2 developers, I don't see it happens soon.

So, why? Anyone have asked this question previously?
I don't believe such a great project is not innovative and interesting to game publishing companies.
