My impression is - they're rebooting the whole universe, when everything collides. And the result will be a mishmash of worlds and realities called "Battle World." (So Earth is going to be this mess of different pieces; and will no longer really resemble Earth). Heroes will be from all kinds of time lines. And from the video, potentially multiple versions of the same heroes.

And the video seems to lend to the idea; that all books are being rebooted into this Battleworld. And this this WILL be the new Marvel Universe from here on out.
