"Level-5 has talked in the past how Professor Layton and the Azran Legacy, the sixth game in the Layton series is also the last title. But as long as a series makes money, I think we can expect it to continue in some form, and Level-5′s boss has said that, "If a seventh game was to be born one day, it probably won't be the Layton we know today."."
on a Nintendo blog website..
So it may not be the end.
I wonder what happened to Luke at the end of the Lost/Unwound Future, the game said that the story was "to be continued"..
They can't just end it on a cliff hanger, right?
