Gamification and Big Data walk along together (see this other post about the Horizon Report 2013 - Higher Education Edition and also Four Approaches to Collecting Data in Gamified Systems). It is also worth to look at what Gartner predicts about the future of these two technologies. In the 2013 edition of Gartner's Hype Cycle for Emerging Technologies (which I got from here, a link shared by Andrzej Marczewski) and in the 2012 edition we can see how the two technologies are evolving. They are now both at the top of the "peak of inflated expectations" (Gamification is a little ahead). They have an horizon of 5 to 10 years to reach the "plateau of productivity" (in 2012, Big Data was in the 2 to 5 years horizon).

And to end, a funny video about how gamification is already part of our lives ...
