I got up at 2:00AM in order to be one of the first to order the nMP back in December. It arrived in January and by that time I had received the six Apple TBolt monitors. The monitors do not actually work if they are daisy chained, they must each be plugged in to one of the six TB ports or they will not work. Yes, I did test various methods of chaining, and yes, I did have conversations with support who has not gotten back to me with any comments or suggestions. An additional problem with using six monitors is that if you have a number of screens active (such as in a trading application) and you exit the program, when you reinitialize the same program the screens come up on various different screens than the ones that were being used when the program was shut down so you have to move them around every time you bring that program up. Support and I tried various configuration alternatives but couldn't find a solution. This same problems occurred with the previous MacPro system factory supplied with two x 3 port cards. When used with six 30" monitors the screen contents did not retain their positions. And one more thing. If you picture six monitors in two rows of three monitors each, each of the three (vertical) pairs of monitors requires a structure to support the monitors so if you have three sets of two monitors there are three hefty supports behind those screens. The thunderbolt cables are fixed to the monitors, not removable. These cables are short enough that finding a place to put the nMP in order to be able for all six monitor cables to reach the ports is a big problem since you have the monitor supports behind the monitors. I was able to place the nMP with no extra cable to spare but the cables are really too short and there are no extension thunderbolt cables that I am aware of.
