The “news” here is that Star Tours is will be adding a new location from The Rise of Skywalker, but the actual news is that we get a name for where that Death Star wreckage is: “the ocean moon Kef Bir.”
The planet is new, but it’s already on Wookieepedia thanks to a mention in Ultimate Star Wars, which has another connection to someone new. Possible spoilers, if you consider really basic things spoilers.
