It seems mine only took about 36 hours from the time I selected the Reserve option. I do not know exactly what the number on the right means but I am thinking it is the amount of download finished and my be some type of minimum before the install is offered.
Well, the system installed without problems. The number is just the size of the download which starts when you select Get Started.
Looks like the message on the Microsoft site may have been to discourage questions about the download temporarily. Or they changed the process and were not pre-downloading the required files.
