I don't see this ever happening. I think she will still do a huge tour (hopefully starting at some point in 2022) for her next country album. The Vegas residency, if true which I think it is, will only be a side project. Lady A did a Vegas residency that was a total of 15 shows. Keith Urban's residency was 12 shows, and they were adding more but then got cancelled cause of covid. So a Vegas "residency" doesn't have to mean an artist is doing a ton of shows in Vegas all the time.
I will say this, though - even though My Savior is so brand new, I am hoping for a new country radio single by this summer!! Doesn't mean an album would be done or ready, but she could have an early lead single, like how Cry Pretty came out 5 months before the album.
