Probably has to do with quality. The first two of the Green Day trilogy were considered pretty poor amongst fans, whereas Coheed fans, for the most part felt that the Afterman was a return to form for the group.
Agreed. Definitely was impressive for them to sell nearly 100k between the two. But 20/20 Pt.1 for JT has obviously been crowned king and has sold a ton since the first week. I wonder if all that push with this release can make him do 1m+ week one. Would be really crazy if that were to happen
