I think the difference is, we are talking 10 years, not the 20+ that Madonna has been in the business.

That would put Kelly at right around 13 years in the business - with so much available to her, I can see her still being wildly popular, although maybe not as much in mainstream music.

I see her having a couple of Broadway shows under her belt. I see her writing songs for other artists launching their careers. I see her with atleast 4 more wildly successful albums under her belt, and her being able to tour and pull in the crowds (larger than we even see now) night after night (think Cher's farewell tour).

I see her with multiple grammies under belt - for singing, for writing, for albums as a whole.

In other words: I see her as having it all.
