JSON likely will be around as it is extremely simple (technologically) and extremely light (in terms of network usage). In order for a JSON killer to appear it would inherently have to be superior to JSON, and it is very hard as for what JSON is used for it does very well indeed.
JSON somewhat replaced XML, but that made sense since XML is more complex and a lot more expensive (both in terms of network AND processing).
I can see people building more complex obstractions on top of JSON in the next for years (essentially re-building what XML was, but in JSON) however I cannot really see JSON being entirely dethroned for what it is good at.
