I'd like her to do that but it would be too predictable so I don't think she will attend. If so she will look as someone who wants to be honoured without doing anything for it. She attended last year to show that she was okay (I personally see it that way) but this year it won't be so unexpectedly and so appreciated.
I think it would be good for Shania to attend as I'm sure the other artists would enjoy catching up with her and it might be a while before we'll get to see her do any public appearances, seeing as the music is taking long to come together.
