Watch For…

Secret Wars House of M
We’ve seen Lorna on a couple covers now, and the MODOK cameo above alongside those covers makes the chances of her having a meaningful role in this HoM very promising. But, we haven’t seen any definitive proof yet in the form of pages or solicits, so we don’t know yet if she’ll be in it or how much. This is why I put it in its own “Watch For” category.
Release dates are hard for me to pin down. I see one for August 19th for House of M #1.
