P.J. McNealy of American Technology Researchers thinks that the PlayStation 3 isn't going to see the assembly lines until at least another month. "We don't think [Sony] is going to be in assembly for another four to six weeks -- end of July, early August," he theorized at the MI6 conference.
While he didn't say that Sony would miss their November 17th deadline, he did hint that the complex nature of the console will limit the yields they can come up with. "This is now the most complex box that's ever been built in this industry. It's going to have a Cell processor, it's going to have a Blu-ray drive. The number of pieces that are going into this box are even more astounding [than the over 1700 parts used in the Xbox 360]," explained McNealy as quoted by IGN. "While Sony has certain manufacturing advantages at the end of the day, this is a very complex process, and they're going to be limited to the yields that they can come up with."
Sony's stated goal is to build six million PlayStation 3 units by the end of March 2007, and a monthly shipping target of one million per month starting with the November launch.
