Today I was just on the runescape wikia site looking at the recent images when I noticed this:
Whats interesting to note is that the area is bigger, the bridge to the tower is shorter but the path north has been made bigger. Also if you go to the download section and look at the entire world map, Tutorial Island will no longer be behind it. As they has said that Tutorial island was to be removed in way for a wizards tower rework. Expect this update to occur on the 26th November
