While it hasn't been officially announced, Star Wars: The Rise of Skywalker and The Skywalker Saga collection can now be purchased on such digital platforms as FandangoNOW, Vudu, and iTunes.
Those of you sheltering in place with youngsters will likely also be pleased by this non-Star Wars digital release news:
This surprise from that galaxy far, far away arrives shortly after the news that Disney will also be making Frozen 2 available on Disney+ three months early on Sunday, March 15, due to the COVID-19 pandemic, which may be the cause for this early release as well.
I personally just purchased the UHD version from Vudu. Now leave me alone. I need to watch it.
