I still in my heart of hearts think that she's working on a new album too to be released at some point next year. She's been doing so much writing; it can't be for 6 xmas songs.
I wouldn't be surprised if she wanted to release her xmas cd, have a baby, and come out next year with a regular album. It's an ideal situation, especially if the Xmas cd does decent (Gold/Platinum during Xmas)
