I "reserved" weeks ago, and so far as far as I can tell I have not seen any unusual network activity. I assume it is not DLed yet, as I have not gotten a "upgrade now" prompt. Currently, I have 0 network usage, so it is not DLing. So I do not know what is going on.
I recently heard you could just download the ISO and do a clean install, which I would much prefer anyways. I did this, but apparently there is no way to get a licence key without going the upgrade route. So I already have Windows 10 installed on another partition, but I cannot activate it until my reservation does something...
