I doubt this a lot. I hear about that India thing for the first time, and it has nothing to do with the release date of an album - a weird article again.
Katy doesn't seriously write while on tour, the tour has been too long and exhausting and won't end before it's nearly Christmas again. She may be jotting things down and experiment in a studio, but I believe no serious work for an album production will be done before the beginning of next year, and Katy wouldn't be in a rush to throw something hurried and half baked on the market.
But if she manages to create an album in that time which isn't a disaster but a success then she's even more superhuman than I've already taken her for.
