Kylie possibly quitting pop after Showgirl tour?

Reports suggest Kylie may be considering ending her pop career after her up coming Showgirl tour - though that seems to be based on a very vague quote in an interview with GQ that actually says very little: "My life has been very full and rewarding but I've been doing the same thing for a long time. And yeah, there is something missing. There's a number of things missing. But I think they're coming when they're meant to come. Now I'm focused on making the tour a success. I'm determined to do that and then we'll see where life takes me."
