than "have a fixed roadmap to ...", it's sort of a general brownian motion).
None of them, that I know of, have ever mentioned TLS 1.3.  In the same way
that HTTP/2 effectively forked HTTP, so I'm expecting TLS 1.3 to fork TLS.

>Again, what timetable do you think that will happen?

In SCADA, embedded, etc, I would say "never".  I know that predicting the
future is always risky :-), but if I had to put money on "1-2 years", "2-5
years", "5-10 years", or "beyond ten years", I'd put it on the latter, which
in effect means "never".
