So judging by the solicits, the Knights are made up of Moon Knight, Shiang Chi, Daredevil, Iron Fist, and Dr. Strange. That's a good collection, although I'd like to see a female character in there somewhere. But I wonder about Daredevil including Dr. Strange, as he's clearly just as inexperienced as Peter, and Daredevil bitches Pete out any time they get near each other. Actually, I imagine DD will assemble the others and then Dr. Strange will be a big last page reveal, one now ruined by modern solicitation techniques. Ah well.
DD is the one ultimization that I enjoy seeing written pretty much in line with his 616 counterpart. All the characters that have their own books should be as different as possible from the 616, but since DD is pretty much only present in the context of Ult. Spidey, I think it makes a lot of sense to write him without any major changes to his age or characterisation. I think an Ult. DD book would be superfluous, but I wouldn't mind seeing him as an occasional mentor to Pete.
