Gartner puts Gamification on the hype curve
And positions it well I think.
The hype curve s a graphic representation of the adoption and maturity of a specific technology. Garnter puts Gamification just shy of the peak of hype. Then comes the trough of disillusionment where people actually start measuring impact and most of the hype sellers are weeded out.
In short: In about a years time the hype sellers might, finally, be gone and we can start selling real, measurable, gamification.
