Just a heads up. On Wednesday, January 28, SNCF begins the sale for tickets with travel dates from March 30 to July 3. If you want to grab some cheap tickets, you might want to take a peek. ๐

From December, Italy and Germany will be linked by direct high-speed Frecciarossa trains, between Rome & Milan to Munich. It's possible because of a partnership between Trenitalia, Deutsche Bahn and รsterreichische Bundesbahnen (because it has to pass through Austria).
Milan <-> Munich ~6:30h
Rome <-> Munich ~8:30h
Future plans include extensions to Berlin and Naples by 2028, and there are discussions for Italy to Vienna too, but nothing concrete yet.
