We're overlooking the important point here: the band essentially "sacrificed" this album by giving it away, likely because they've been gone for so long and had to reintroduce themselves. This is basically a downpayment on Songs Of Experience, which is going to be tied into a new interactive media which they hope people will buy.
They're obviously hoping enough people like this album (as well as the subsequent tour) and will be curious enough about what they do next, which will be coming in a shorter time frame.
I honestly don't think they expect this to do well, or care. This was a transitional/experimental period release-wise, and it's all about where things go next.
