Sure, and the single CD at 9.99 is a good deal, which is what the non-hardcore fan would buy. In my opinion there is no doubt the 2CD set is aimed at the hardcore fan, bear in mind some hardcore fans already have already shelled out for the albums (in multiple formats for those us who were around when they were on vinyl) so it does seem to be taking advantage somewhat to me.
This gets back to my open question about whether U2 understand what a "hardcore fan" looks like. They really might not have any frame of reference for this. They probably consider themselves hardcore fans of certain groups, but they are probably not even in the same ballpark as we are (as far as chasing down every track, following news/discussion daily).
