Back on September 25, DisBoards user zoo2tycoon reported that PizzeRizzo will close permanently on or around October 20th. The story circulated for a week before WDWNT.com picked up the story. They are reporting that beginning October 20th, PizzeRizzo will change to seasonal operations until Star Wars: Galaxy's Edge opens in late fall 2019.
It is unknown if any changes to the restaurant will take place during that time. Our full rumor tracker for this can be found here.
