Hell yea!

So I recently asked Dwayne McDuffie, the current writer of JLA, if he would ever address the fact that our favorite superheroes were married briefly in an alt universe and he actually said YES. Looks like there maybe some more SM/WW moments in our future...

He also had this to say in response to moonshine13's question:

So my question is why do writers repetitively play with the Superman/Wondy pairing if it is not meant to be?

Because it's intriguing. It probably won't ever happen in a permanent way, but there are lots of fun stories to tell about it, and every so often, we'll tell one.
