Nah, it'll just be Zelda DLC. Doubting any new games. They'll advertise Xeno2 and Mario Odyssey bundle through December, then announce a direct on the 7th or 8th of January.
Zelda DLC will probably be out buy Game Awards, remember they showed Zelda BotW in game awards 2014, so I definitely think there are good chances they will one big Switch game. One announcement at Game Awards in December don't go against January Direct in any case.
