And it's about time. Not only did Tarek and Christina split up, but the show was becoming tiresomely repetitive. They kept trying to top their last snatch-victory-from-the-jaws-of-defeat success, but it started wearing out. And it was obviously at least loosely scripted, as nearly all so-called "reality" shows are, which made it seem much less spontaneous: http://www.wnyc.org/story/258741-reality-tv-even-faker-you-think/

I'm surprised that there are so many spin-offs that are still airing. This was the best of them, I think, and it got a lot done in just a half hour. I tried watching some others, but they just seem like more of the same. I wore out quickly and I will drop the entire genre after finishing the last few episodes of Flip or Flop--hoping that there will be something a bit fresher there before it ends.
