Due to the arrangements coming together rather late in the process, we're not planning a CoverItLive event on the announcements this year; besides, except for Dave McCarty — who as Hugo Administrator will be too busy on Announcement day — none of the Hugo Awards Marketing Committee members are going to be at any of the Announcement events. I'll be watching them, however, and posting the nominations shortly after they're announced at TheHugoAwards.org.
Note that Loncon elected to go with the terminology "Hugo Award finalists" rather than the traditional "Hugo Award Nominees." I think this is the right decision now that people have got it into their heads that one person writing their name on a Hugo Nominating Ballot makes that person a "Hugo Award Nominee" despite more than fifty years of contrary practice and tradition.
