I honestly don't know. Her singles are not taking off and her promo songs aren't igniting with listeners. That usually ends up saying that there is little to no interest for an artist. Add to the fact this album has little if any pop/world hits and I think she has her work cut out for her. Even promo can't make people buy songs that aren't catchy and that people don't like.
I fully expect her to sell 300k first week out due to the positive feedback the I Am era generated. But she has like no support from pop this year. Run The World performed terribly, 1+1 did horribly too and Best Thing I Never Had is struggling up the charts and is still pretty low on iTunes (last time I checked it was #94) I still don't think it's going to hit. There is no way her album is going to have longevity if her singles don't impact. So I see her dropping off if her singles don't start hitting at some point. I honestly see this album scanning no more then 1.5 million worldwide if it doesn't a hit.
We shall see. I see a lot of assumptions being made but at the end of the day it's all just speculation. We'll have no definitive answer until the time comes.
I think it'll sell 300-350K first week, and perhaps it will quickly match FF's slow sales, but I don't think it will go Platinum without a re-release. If I Wanna Go is a hit, FF will probably go Platinum.
