In the article below it was confirmed that the Sundering adventures will be platform agnostic with editions specific details available as free download:
Sundering authors R.A. Salvatore and Ed Greenwood are also collaborating with D&D’s designers on new game content. They’re each providing the story and helping write a new playable adventure that will be released in 2013, allowing D&D players to be heroes of their own Sundering adventures.
Since the D&D game is in between editions, these new modules will strive to be “platform agnostic.” The idea, says Mearls, is that both books will focus on providing story, color and characters, so they that can used by players using any version of the game. Edition specific details –like statistics for monsters– will be available separately, perhaps as a free download."
