Simply because it won't be like Christmas - people will end up wishing they hadn't signed up if the download takes a long time; if their system gets screwed; if they hadn't made good backups; if they don't have enough space; if the installation just doesn't finish, and a million and one other things that won't work out of the box as expected.
Hope they give some warning of a type: "We are ready to download files for upgrade, Y/N/Later ?" so it doesn't catch people unaware and can plan download and installation at their leisure like overnight etc.
I live in New Mexico, what time are they going to be starting all of this stuff on the 29th?
One group of people who may be disappointed are those with the MCE - Media Center Edition - I am not 100% sure, but I don't think they will be able to upgrade, only to perform a fresh install. Can anyone confirm this?
