Next era is going to be such a flop compared to 1989, no matter how well she does. There's no possible way she can open with more than 1.2mil. Over a mil is attainable, but no way she can do more than 1989. She definitely won't push all the way to 8M because sales are going to be dead and gone by then. There's no way she can get more than 3 #1 singles, and 4 or more radio #1's? Oh lord no.
but as long as she serves us an even greater album than 1989, I'll be happy. She's had more commercial success in one era than most girls could dream of for their entire career
