XC60 Diesel without Adblue a problem for the future?

Hello, I love it with an XC60 diesel from 2016/2017. Almost as an annual car or a young used car. Now they all have Euro 6, but no adblue. How do you see this for the future? Of course, nobody knows how to continue with the diesel at all. But I also don’t want to invest 30k and shortly there is a problem driving currently two Golf TDI with Euro 5 and the scandalous engine, that’s enough for me. From Sept. 2019 there should be no new registrations without Adblue anymore. W You can see that if you can say anything reasonable about it.
