You cannot judge the success of a comic book anymore by floppy sales, because believe or not, they actually make up less than half of all comic format sales. http://comichron.com/yearlycomicssal...ustrywide.html
Seems trades actually make a significant amount more than floppies in recent years. To the tune of $200 million more than floppies, and growing every year. Also shockingly digital sales has seemed to have leveled off in recent years.
