They will have one hour or more, depending what time MJ's segment airs.
In America (For some unexplained reason) Chart week starts on Monday and ends on Sunday. But most records are released on Tueday, missing that first day sale in their premiere week. Coldplay will bypass that rule and release their album this coming Monday.
you can't seriously expect the label to keep throwing money at this project if they won't have a sizable return. The millions they already spent to produce the record and all the huge marketing, all that resulted in 150K sale in US and maybe 40K in UK (the two biggest markets). I believe they will pull back, unless LNFSG picks up some steam and become a hit, that could sustain album sale.
Similar to what happened with "Michael". It is sad because LA Reid , who just started at Epic, took a huge gamble with this project. we can't expect these huge scale projects if fans don't fully support them. I am sure black Keys label didn't spend half as much money on their album as Epic did on MJ's.
I hope US fans are able to turn this around during the next 5 days.
EDIT:
OK...I just re-read my post and it came off a bit more negative than I intended. Xscape is not a failure far from it, being #1 in over 50 countries and #2 in US, Germany (if those stand)...is a great achievement considering the negative press and critics who don't agree with posthumous CDs. Xscape has already exceeded "Michael", if not by numbers, by the enormous positive press coverage.
This is more an indictment of the current music market and fans who claim to want large scale projects, but are not willing to put their money where their mouth is. And no need to mention boycotters, because Xscape through its global success has proven they may be a vocal group but hold little to no power.
