That being said, this does not mean we can't add more dungeons that take place in the cogs, more public areas in the cogs, more cogs wilderness areas, etc. It's just that any future cogs related content will either be part of the Masterminds of Sharn pack (not likely) or not physically located in the Cogs wilderness area that is being released with U42.
