When my organization made the download available, PRO was able to find that an update was available. I know this didn't happen the second the release was announced, but a few days latter. I don't know if your administrator has to approve the release of new software for download or not. I would suspect that the organization administrator would be responsible for this, and not esri. You would want something released within your organization unless you were ready to deal with new versions etcetera.
Worth a check, if you are connected to an organization.
