Here's an interview Waid did about the Champions/Avengers crossover:

It seems they're doing the only story I don't trust them with. They might shove in some conflict around Vision's actions in Uncanny Avengers ages ago, but that was so OOC it's barely canon. I guess it could end with Vision and Viv hugging it out and getting some therapy finally, but Waid does love to make poor Vision an antagonist, and anyway the only person I trust with Vision fallout is Tom King, who's not coming back for a long while.
Coupled with those rumours about the Champions turning into a team led by America Chavez with every member except Viv, I'm pretty worried right now. I just want my faves to not be ruined.
