I think it's rather impressive, that she isn't going to use X Factor as some cheap ploy to flog her material. Cheryl did it and Nicole did it. She really just wanted to do this, and if she doesn't feel she "needs" X Factor, then all the more power to her.
Would it be great promotion..yes.
But it's also bad ass, to have X Factor AND Glee at your disposal and to bank on your own worth, rather than the leg up they would give you.
I hope she doesn't to be honest, now people can't say "Oh she need help with her sales...blah blah"
