Thanks for catching that! It looks like they launched a new design for http://www.gnome.org/ in conjunction with the release. That must have altered the URL for the press release they had published earlier in the day.
I'm unclear on how the changes relating to the desktop will actually change the experience.
Congratulations to the Gnome team though! It does look great.
