As someone mentioned in a thread @JOL, With the economy and the market like it has become , this could happen to potentially any investor/developer.
I seriously doubt Mr Kuhn embarked on this endeavor, with the intent of ending up where it stands now, and as stated, I dont think this is the last we will hear of him. Hopefully he can initiate a plan B, and emerge from this, somewhat without losing everything. I feel it unfortunate , to say the least that he climbed so high, then fell. I wish him the best.
