He is probably as miffed as everyone else why the project hasn't seen the light of day.
In Russia, we have a song "Zvezdy ne ezdyat v metro", meaning "Celebrities don't ride the subway". I think people like this are just too cool to answer emails
I think everybody universally understands that the project is on halt, or at least in the very slow development, so it will be ready only when it's done. Hence no answers from anybody.
