"You’d think it would be a continuation of the gospel theme from this year as more episodes of the drama are released."
There's no reason that they couldn't tie that theme to the life and ministry of Jesus. They don't have to be tied to a previously released title by that name. These days, they're switching things all the time. Heck, the century old requirement to count time was summarily dropped like a hot potato!
But you might be right; Jesus might only be flavour of the month this year. I thought that the increased attention on Jesus might be a long term thing: "Sure, show affection for Jesus, who isn't here yet*, but more so, show affection for and obedience to Jesus' brothers (the GB), who are here.
*But he came invisibly some time ago. 🙄
