*Missing details here, and most likely, a lot of other places.
So, 32 down, 20 to go.
There are rumours of a Legion of Super Heroes title (that are a little too rumour-ish to put here just yet), as well as former WildStorm titles like Grifter. There are also rumours of Grant Morrison on a Superman title, and Action Comics hasn't been announced, and I can't imagine they wouldn't be continuing with the comic that Superman debuted in.
Will update as more information comes to hand.
UPDATE: The aforementioned Bleeding Cool have a more up to date list here: http://www.bleedingcool.com/2011/06/07/an-updateable-list-of-the-52-dc-titles-for-september/
