Bumping this to mention that the Extended Edition came out today. Apparently, it's a free upgrade for people who already own Hong Kong. Looks like it has a bonus campaign as well as a list of "improvements" for the existing content. I'll be checking it out once the download is done. It's pretty cool that this was free instead of a DLC that costs extra.
