Bookmarks for existing Mapplets will continue to work. They will be automatically redirected to the new Mapplets page for the relevant Mapplet. (...) However because the Mapplets page is not part of the Google Maps application, Mapplets will no longer have access to Google Maps user profiles. (...) The above changes will be made on or shortly after Wednesday December 8th 2010.
