I heard this over the grape vine, looking for a transcript of Mearls "Future of D&D" Keynote.
Planescape, Dungeons & Dragons, their logos, Wizards of the Coast, and the Wizards of the Coast logo are ©2008, Wizards of the Coast, a subsidiary of Hasbro Inc. and used with permission.
Looks like this is the case.
I'll try to find the exact point it gets mentioned in the keynote, which is here:

ETA: He mentions the old settings at about 38 minutes in.
ETA 2: Greenwood mentions the Sundering will, over the course of 6 novels, "set the Realms right".
I'm assuming this means removing the Spellplague's effects, but will it create two divergent timelines in the process of making two parallel worlds? Or something entirely different?
