Here are a couple of articles you might be interested in. J&K/TLC have announced the 5th season of their show --- along with a possible trip to Korea (or at least that's what the speculators are betting on).

'Jon & Kate Plus 8' gets another season: Are we happy?
Apr 2, 2009, 05:02 PM | by Margaret Lyons
So Jon & Kate Plus 8 is returning for a fifth season. Um....yay? At today's TLC upfront, the parents were on hand to offer generic platitudes about the upcoming season. Jon said to "expect the unexpected," and Kate added that "[the family will] be taking a very exciting trip in the near future. Not to give it away, but it'll take us back to our roots." Oh man, I hate "trip" episodes.
I'm not sure that I want another season with the Gosselins, and not just because they often seem, oh, completely miserable.* Also because what I used to like about the show has diminished in recent seasons: I liked the documentary vibe back in the day, when the show felt like it was capturing an unusual family doing ordinary things. Now, so much of the show is about the show itself -- there's a meta element here that's just not my style.

'Jon & Kate Plus 8' to return for fifth season
Apr 2, 2009, 03:59 PM | by Lynette Rice
TLC announced today that Jon & Kate Plus 8 will return for a fifth season. The popular show that attracted record ratings for its March 23 finale will join a busy roster of returning programs, such as 18 Kids and Counting, A Baby Story, American Chopper, What Not to Wear, and Little People, Big World.
The cable network has also introduced a host of new series -- more than 19 in all -- that will help fill its schedule in the coming year. They include The Little Couple (a series about newlyweds Bill Klein and Jen Arnold, both of whom are under 4-feet tall); Freakin Fabulous With Clinton Kelly (a fashion show based on his book of the same name); Making Over America With Trinny & Susannah (featuring the original U.K. hosts of What Not to Wear), The General (featuring an interior-designer-turned-contractor), and Mom, Inc. (a new series from Kelly Ripa and Mark Consuelos that helps struggling entrepreneurs).
