For the last two years, Jingle Bells, Jingle Bam has replaced Star Wars a Galactic Spectacular from around mid November to 15th/16th December, when they have started showing both shows up until the end of the year. This date has coincided with the release of a new Star Wars movie (I think).
On the page of the Star Wars Guided Tour, this now appears as a note under the info about SWaGS:
Experiencing a reserved viewing of the obi-wan and only Star Wars: A Galactic Spectacular nighttime fireworks event (which takes a break from November 6, 2018 to January 6, 2019 when the Jingle Bell, Jingle BAM! Spectacular is on display instead for your holiday enjoyment).
That info doesn’t seem to appear anywhere else yet, but it looks possible that SWaGS won’t return until after the New Year this season.
