With the amount of things they are still working on, and the amount of patches they have been pushing (sometimes multiple patches a day), I wouldn't be surprised if they are going to be putting the same patches on the "Live" servers this whole time as the beta servers are not the live servers. So then as they patch the beta servers they also patch the Live servers. This way they could run beta right up till the "3 days early" if they wanted. Come the first day of the early birds they just swap over to the real servers and away everyone goes.
