Technically it already was posted. From what I have found out, Microsoft had the link up for a small amount of time, and then pulled it because there where so many users. Apparently, they will put it back up "Officially" when they get more servers hosting the ISO's.

For the time being though, you can download it from one of the links posted back on the third page:
X86
http://download.microsoft.com/downlo...FRE_EN_DVD.iso

X64
http://download.microsoft.com/downlo...FRE_EN_DVD.ISO

As far as keys go, I would assume that you will be able to get them whenever they "Officially" re-post the download on these two sites:
