The cover Captain Marvel and Black Panther and that they said past and present Avengers and there was a mention the connection to Voyager might have something to do with Blue Marvel and Sentry. End of Ultimates Spectrum and Adam were an item.
I believe it also mentioned Red Wolf. (He's of Occupy, even though they didn't have a name.)
Other than Voyager being another retconned insert, I don't really see a connection to Blue Marvel or Sentry.
The three titles (Avengers, Uncanny Avengers, and USAvengers) are being merged into one, weekly Avengers book. Ewing is a part of this. However, what really made Ultimates Ultimates were Blue Marvel, Spectrum, and America, and they're conspicuously absent from the cover.
We'll see... I hope.
