I'll put this off until I really need it. My Internet connection isn't that great here and it would take forever to install all apps. Otherwise I can happily do without CS7/ CC for now. Not much there that would get me excited (not just in AI...)
At this time, it is not listed for an update on the adobe manager. I am thinking they are waiting for business hours to start. Which means I have to wait another full day. I am on the net late at night.
You could start downloading the apps right now through http://creative.adobe.com. You could get an overview of the new features of CC apps at http://blogs.adobe.com/creativecloud/major-update-to-adobe-creative-cl oud-now-available/
