Roar could perform like BTW, or worse. Prism might not have any other hits on it. This era could still end up a disaster for her. Look at Britney. HIAM broke records and then her album went on to sell 3 copies.
All this bragging now could come back to bite the Katy Kats on the ass. It's exactly why Gaga is getting dragged now.
Britney is (a) mostly a nostalgia act who can no longer use her breakdown to stage comebacks and (b) more terrified of promotion than drug tests.
Comparing her to Katy is pointless. She's going to be promoting everywhere.
