Beyoncé is doing well selling out those stadiums across mainland Europe. For someone who was "never global !1!1!1!!1" this makes it even greater an accomplishment.
Since Prism era, Katy has accomplished nothing outside Super Bowl (which did nothing for her career, no songs top10 on iTunes, over shadowed by a prop and missy Elliott)
The machine behind her hits - Doctor Luke - is now gone too.
Why are her fans so secure that she's "COMING!" next era?
