Ares was in essentially the entire run of Dark Avengers, barring the last issue. So yeah, the need to make him to complete the team. Marvel Boy isn't so necessary since he quit the team early on.

Sentry is coming supposedly in a 2pack with Spidey, although it hasn't been solicitated yet. I imagine Ares will either be in MU wave 12 or a 2pack with either Dark Ms. Marvel r Sentry (makes sense considering Siege) to complete the team.

Dark Ms. Marvel was shown at Toy Fair and was a contender in the Marvel online comic subscription poll. Even though she's just a head swap, I'm sure she'll make it out somehow.
