At MagicBand On Demand stations in Walt Disney World, a few new holiday themed designs have appeared as of November 2nd, 2016. I found these in Disney Springs at the Co-Op Marketplace. One is Christmas Star Wars and the other is similar to a dreidel design. The others are from The Nightmare Before Christmas.
If anyone sees more designs added, please send me an e-mail so I can add them to the site.
