How should it be done? Should it be done in a manner like the past ones, with the Avengers commenting that the heroes seem different than they remember them like how they deal with different Squadron Supremes? Should the original JLA-Avengers have its exact story retconned a tad?
Should it be done like AVX with tie in fights, but done in a way that ensures that an equal amount of DC characters win when compared to Marvel characters?
Who should write it? Johns? Bendis?
Who should draw?
