Not much, as far as I can tell. I don't know what hippie's talking about, actually; I'm just as bored with the "major changes" DC's instituting as I am with those of Marvel at this point. Flash: Rebirth is nothing more than a regression, Batman RIP is a nostalgic romp through the ******ed Silver Age stories that never made any sense and everyone was happy to forget, and Justice League still isn't the all-star team it should be.
I get the feeling that that team we saw with Doom, Loki, Emma Frost, et al. is actually going to wind up saving the day in Secret Invasion and, consequently, Marvel's fickle, ******ed citizenry will declare them the premiere 'superheroes' and treat them like royalty while the actual (kinda, anyway) superheroes get s*** on for failing. Dark Avengers follows whatever stragglers of the hero community are left to oppose Doom's New Avengers, and Mighty Avengers changes its direction to something else.
All pure speculation on my part, but wouldn't it blow your mind if I'm actually right?
