To my knowledge, OH 3 is not even usable yet.

A reply, but not an answer, is it?
Like @lblabr I would like to read into concepts and outlines of things to come

The concept has not really changed, biggest change is made to the UI.

i defined a sitemap how do i get the sitemap displayed ?

AFAIK BasicUI with sitemaps is still supported in openHAB 3.0, but this might change.
