Riri and Nadia joining doesn't surprise me, as they're almost certainly gone from Iron Man and Avengers when those books change creative teams. Cyclops will presumably be written out in #18. That issue will probably also confirm that the two new team members are around long term (though Nadia requires a timeskip at some point during Champion For a Day, as she can't join officially before No Surrender), while dismissing Red Locust, Falcon, and Patriot. This news also means that Amadeus will probably lose his solo book to Bruce, but not be depowered. I assume Planet Hulk II and World War Hulk II (his current and next solo arcs) take place between #18 and #19.
