Just to poke the bear a bit, thats not exactly true, at least for the most recent sales figures for December from Diamond Distributors. Marvel is getting its ass kicked by DC at the moment, and some speculate its because long time fans arent picking up the books that gender swap their favorite characters.

I personally dont collect comics anymore, and havent for years, except The Walking Dead, but if they screwed around with my favorite heroes, I sure as hell wouldnt buy them. When they made spider man go crazy, ripped the adamantium out of wolverine, broke Batmans back, and killed Superman in the 90s...thats when I stopped collecting. If they are doing an alternate print, thats not the main contiunity, then maybe, but the actual one? Nah... Marvel is also doing some pretty crappy stuff regarding canceling books because they dont own the movie rights to them, which is super shady as well. Its a business I guess, but still. I dont think rampant greed is an excuse to be a shady company and be a jerk to your fans. Kinda sucks but whatever. :facepalm
