According to an article on the Blizzard Entertainment homepage, the Starcraft II Collector Edition will be including (but not bound to):
"Exclusive Battle.net downloadable content, including special portraits for your Battle.net profile, decals to customize your units in-game, and a visually unique version of the terran Thor unit"

The details on the release version of "exclusive Battle.net downloadable content" is vague at best, and future plans of this exclusive downloadable content (DLC) is non-existent to my knowledge.
Do you have any ideas, opinions, or news about the release and/or future planned (exclusive or non-exclusive) DLC?
