There was a lack of #1s this September and it hurt the market. The past two years DC had their 3D covers that boosted sales, and this year the latest round of Marvel #1s will not hit in full force until the October and November numbers. That being said, I know that the LCSs I talked to were dropping their non-file orders on the new Marvel #1s since the Marvel Now relaunch over the past two years was a dud both on the shelves and as back issues (and I expect the latest round of #1s to do the same).
It will be interesting to see how Marvel's latest relaunch turns out. I skimmed through the ASM vol 4 #1 last week and it was bad from both the story and artwork perspective. The only thing to like about it is the Alex Ross cover. I have not read any of the other titles, but if this what Marvel books are like now I can see why the sales are flagging. After the initial bump from the #1s, I can see the titles dropping off substantially again just like the weaker New 52 and Marvel Now books did.
I am also surprised at how many books from the big 2 are selling in the 30,000 copies or less per month range and are still being released. What is the break even point number of monthly copies on a title?
