Ya beat me to it.
I really wish we would have gotten some -300's before they shut the lines down.
Boeing developed it five to ten years too late. After Boeing got their CATIA system up to design the 777 and 737NG, they seem to have used it to develop all the derivatives of various models that had been proposed but not previously implemented. The 767-400 never got any orders other than from Continental and Delta. The 757-300 sold only just over 50 copies.
