I think Cho is trying to imply that Shanna and Logan don't get along--or won't-- with that comment. That is the only thing that would make sense about that line. As for where Kevin and Zabu are...I assume one will find that out when they read the comic.
I was glancing at the Marvel Now teaser poster...the original one from like two months ago. I did notice what Slott and others have pointed out about Spider-Man's costume. It does look different. Peter looks like he has some kind of weird metalic apparatus along both arm spans and his costume looks tweeked a bit. Darker blue...can't see what he supposedly sees in his eyes though.
