To be fair, Moon Knight isnt a direct tie-in, its a Casualties of War thing a ma bob, which I really have no clue whats that is supposed to mean, but yeah, Finch is off the book next issue anyway, or is #8 the last one? I forget.
I don't know which issue is his last. The artist coming in looks good.
"Casualties of War" I see as pretty much a cover-all for any book to do a tie-in with CW in which the exact timing is shakey and Marvel doesn't deam it an "essential" tie in that is included as a story chapter, but more like a "side story". Which for some of them is a little bizarre as I felt the Iron Man/Cap story was ESSENTIAL CW reading, even if a bit late in the game. Basically, if you just want to do a story and then have said character either "react" to CW or have Cap or Iron Man try to recruit for a few pages, it's a "CoW" tie in. If it basically is another chapter of the CW story from page 1 to 22, it is a "CW tie in proper".
Again, this is shakey, because CW: X-MEN was considered a "core" CW tie in by virtue of, duh, being the X-Men, the general story was essentially a sequal to THE 198 and had very little to do with CW. Like any crossover, some tie-ins are more "essential" and enjoyable than others, so it is a fan's gamble to pick and choose which.
Basically: "CoW" = If you happen to be a regular on this book, here is your character reacting to the event
"CW" = essential chapter in our 42+ part story that will be referenced at any time.
The distintion of which stories are billed as which will again be a little haphazard in some ways.
Anyway, not surprised on the Cho situation.
