I don't think any dealers have been saying the Defender is coming back for the past 14 years. Now the NA LR dealers have been told that the new Defender will be designed with the US market in mind. This was announced at a dealer meeting a few months ago. Of course when it shows up and what it will be is YTD.
In fact as we all know LR could scrap the whole Defender project. Being so far in the future anything can happen. But we do have credible info. for the first time in many years.
