A few months ago,there were rumors floating around that Katy would debut KP4's lead single at the VMAs and kick off her new era but with Rise being released,it's likely that the lead single won't be coming in the next few months cuz she just released Rise and considering that it's NBC Olympics coverage theme song,she would promote it for a while(maybe at the VMAs?).also,it's not really a great idea to release two songs within such a short period of time
I believe her team would wait for 4-5
