Over at Newsarama, Grant Morrison discusses the legacy of 52, and some new directions for the DCU.

And the parallel Earths you see in issue #52 are not the familiar pre-Crisis versions. If you think you recognize and know any of these worlds from before, you’d be wrong. We all wanted to do something new with the multiple Earths so what you’ve already seen in 52 is simply the tip of the iceberg – each parallel world now has its own huge new backstory and characters and each could basically form the foundation for a complete line of new books. If you like the ongoing soap opera dynamics of New Earth, you can watch Mary Marvel turning to the dark side as her skirt gets shorter and shorter, or you can buy the Earth 5 line of books featuring more iconic versions of the Marvel Family. If you miss Vic Sage as the Question, you should be able to follow the adventures of Vic’s counterpart on the Charlton/Watchmen world of Earth 4.

The idea behind the Megaverse is to basically create a number of big new franchise possibilities. It’s like having several comics companies and universes under one umbrella, so, as I say, there could be one book or a whole line of books spinning out of the new Earth 10…. That’s how I’d like to see the Megaverse played out as we move forward. And no crossovers! Each of the parallel universes should exist in its own separate stream with no contact from the others – not until we have a story worthy of bringing them together.
