I actually wouldn't be surprised, mostly because the album will have likely came and went by that time and I don't know how long she'll promote the era. Thankfully she'll be on tour so it might force her to keep pushing it.
But if she goes diamond in the early half next year, how much more push can they do for the album?
I should say though, she'll likely win the pop categories easily. Pop Album and Solo Performance will likely go to her no matter what. Plus Hello will probably win Best Video. The general fields will be difficult.
