The next era will be a success no matter what she puts out, IMO. The big 'drop' (TFM --> BTW) has already happened and who supported her through this era will have no reason not to do it with her next. Her fanbase is still huge, and the tour is proving she is still recognized by the public and has a massive starpower/social-media power (her landing in a country or hitting her head with a pole gets so much media coverage that her album sales skyrocket). Plus, she is having a fourth quarter release which will help her push better numbers (late May release was the worst thing ever). Her image is also in a far better place than it was last year, at least for my personal experience.
The singles might underperform once again (if Pop radio keeps giving her average airplay), but the album is gonna be an hot-seller.
And I'm not here for this being bookmarked and bumped if she bionics.
