I gotta come down on the side of having confidence and faith in the principles knowing best what is needed to be revealed about the progress of this project. They have their risk of $$$ and reputations at stake. They will act in the best interests of success in the project, and when they choose to make certain things public, is fine with me. I think Adam is right, and we don't know how many sensitive details may be involved, from local politics to tricky financing, or even inner circle of developers disagreements. Outter periphery real estate considerations may also be in the big picture. Assembling R.E. packages of land and their local impact and rumor mill stuff is highly volitile in most projects.
So, I am willing to wait and let these highly respectable principles do their thing on their timeline and in their most well considered schedule.
Good Luck!
