Considering that fact that <em>Spider-Man: Brand New Day</em> is going to be releasing between <em>Doomsday</em> and <em>Secret Wars</em>, I do think there's a real possibility that the "Brand New Day" could be Spider-Man waking up in the Battleworld, the patchwork of fragmented realites created by Doctor Doom to save existence which kickstarted 2015's Secret Wars in the comics. It'd be a pretty fascinating premise for the fourth Spider-Man movie, while also serving as some prime set up between the fifth and sixth Avengers movies.
