As someone pointed out, the only reason they have so many orders is because they haven't updated the MacBook Pro in forever. So they are going to have a lot of online orders from people who have been waiting forever and then the online orders will nosedive.
No.
There are many orders because these machines are a great package. The only substantial complaint is from users looking for increased memory resources. This would require a larger, heavier, louder, more power hungry solution with currently available chips. That is fine with some, but Apple didn't do it. It would be obsolete as soon as the chips are released. I sympathize but its just a delay. Cope.
When the chips are ready, increased resources will fit in these chassis. There is a well publicized delay in Intel's cycle. As someone else stated, these chips are on the edge of what physics says is possible with silicon. Cope.
Other complaints:
Ports: 4 x Thunderbolt 3 is awesome, awesome bandwidth. It was just as painful to lose 25 pin serial, parallel, 9 pin din, VGA. Update your peripherals. Why is a much larger machine with a dozen obsolescent connectors acceptable but pick and choose a couple of adaptors is not acceptable? You need every single port ever?

No 4k: Pixel count does not =/= image quality, especially on a notebook size screen. Reread the improvements to the already excellent retina displays. 4 x Thunderbolt natively drives 2 x 5k external displays.
No Dock: Snap out of it. One Thunderbolt cable has more bandwidth than your dock and it charges. A dongle is unacceptable but you want a big ass dock-le?
Price: Don't cherry pick when you compare. Look at the whole package. Get equivalent I/O bandwidth, SSD speed, CPU, memory, track-pad, battery life, quality metal chassis, on a similar size competitor. Don't compare it to machines twice the size and weight. Include the charger size and weight. Post the number. Is it worth the number? Consider OSX with included applications plus walk in customer service at Apple store.
