Honestly I think she'll debut with 200k. I love ha but she's been holding off for way to long and unless she does some damn good promo I doubt she'll hit 400k.
She'll probably sabotage herself by releasing it on Tidal. It's a good strategy, since she knows she wouldn't scrape 150k, and by solely putting it on a streaming service she'll have the perfect excuse for the low numbers when she finally releases on digital and physical retailers.
