This fifth game has Layton and Luke investigating the mystery of the title artifact in Casino City, which seems to have been created by the wish-granting mask. According to a Famitsu report that leaked before the official reveal, there could be major changes to the familiar gameplay system.
Miracle Mask will be out in fall 2010, and may be followed by a second movie, Hino said. The company first has to solve the puzzle of how much money it will receive from the first one.
