I don't envy the decisions the nomination committee has to make, it was a busy year.
As for HoF, to me the no-brainer is the one that started it all, 4-Tris. I'd add Space Patrol, D2K, and Christmas Carol right up there too.
There's roughly 15-16 years of backlog to choose from, so it might take a while to catch up depending on how many HoF entries per year.
