The second single won't be released until right before the album release. And I think it will most probably be 'Judas'. It might not be confirmed but Gaga said it for a reason to the 'Vogue' guy.
Monday 100K slight grammy boost
Tuesday Grammy boost 120K
Wednesday stable 110K
Thursday 100K
Friday 80K
Saturday 65K
Sunday 60k
100K+120K+110K+100K+80K+65K+60=635K
450K+635K= 1.085 Million
My STANLISTIC prediction
I don't think she'll increase. Maybe stay flat or see a slight drop off. And Friday would have been the 200k day, with Saturday doing 150k, and Sunday doing 100k.
The 2nd week at number one is almost guaranteed now. I'm sure she'll spend more than 8-10 there
I'm going to go with 6 weeks. I don't know if she'll be able to maintain her sales over a long period of time when so any people are buying it now, she will probably pass the 1 million mark in total sales this week. 'Boom Boom Pow' had very front-loaded sales and managed to spend 12 weeks on top, so it is possible. I just won't be expecting it.
