The NDC spec is still evolving (and suffering from a bit of mission creep). There's also the chicken and egg problem - airlines aren't going to invest in building in-house NDC based hosting and distribution platforms until there's enough market demand for it. Market demand wont appear until airlines start distributing over NDC. I'd have thought too that the GDS providers aren't exactly thrilled by the prospect of being easily cut out of the distribution chain... There will still be a need for aggregators though since not all travel providers will have the technical know-how or desire to develop their own NDC capable platforms/software. NDC would just level the playing field a bit.
