Apparently this will be a single! A katycat/fan met Katy and she pretty much said she'd make it one! I'll look for the video
I saw that too actually! When a fan voice recorded meeting Katy in Australia last February I think? I'm just wondering when though, I feel like the longer they wait the less hype Prism + Katy's singles will have, so it might not do as well as it could have if it were released more towards the start of the era
Must be the 6th single after TIHWD if at all cause they wouldn't release more than 6 singles.
