Good example would be treatment of jews: The first plan was to get rid of them preferably in their own country (for example madagascar), their ultimative plan to exterminate was "only" drafted in 1941, 2 years after the war has started.
The original war plan was for the third reich to control the people of western europe, which were considered aryan (thats the reason Hitler was so interested in a pact with England prior to WWII, one of the reasons he made Ribbentrop his foreign minister), and to create new "Lebensraum" in eastern europe after getting rid of the slavic people.
So the original plan was "just" europe, but probably this would've changed if the war hasn't ended in 1945 - who knows.
