There is absolutely no chance they would not make a third film, especially the way part 2 ended. It's not like it lost money either, it was a no brainer.
No need for a sequel, but please keep going with Clavell's Asian saga. Tai-Pan has a few of the same characters and Gai-Jin is directly related. They are all great books and would make awesome stand-alone miniseries.
Shogun --> Tai-Pan --> Gai-Jin --> Noble House
Probably don't need King Rat or Whirlwind in there, btu they are good books as well.
