February.

A few call outs:

23. SAVAGE WOLVERINE
01/13 Savage Wolverine #1 - 102,530
02/13 Savage Wolverine #2 - 58,254 (-43.2%)

This seems to be the usual order of second issue drop for the major Marvel Now titles.

...

46. YOUNG AVENGERS
01/13 Young Avengers v2 #1 - 71,254
02/13 Young Avengers v2 #2 - 43,559 (-38.9%)

Pretty standard Marvel Now second-issue drop.

Good god. I know it's first issue collectors and variant cover stuff, but those are pretty devastating "standard" drops.

Some titles are leveling out after that. But not Gillen/Land Iron Man:

11/12 Iron Man v6 #1 - 116,529 (+215.1%)
11/12 Iron Man v6 #2 - 72,902 ( -37.4%)
12/12 Iron Man v6 #3 - 59,041 ( -19.0%)
12/12 Iron Man v6 #4 - 56,708 ( -4.0%)
01/13 Iron Man v6 #5 - 50,899 ( -10.2%)
02/13 Iron Man v6 #6 - 46,206 ( -9.2%)

I'll also note that Avengers Arena is currently coming in around #65 on the chart and dropping 10% a month. So much for shock value.
