At long last, Coro Coro Comics have announced (via 2channel) the winning design of the boss contest: "Clock Genius" created by Gotou san. Details are extremely slim but if the constellation theme in the design is any indication, we might be seeing a new Shooting Star Rockman coming to fruition. Maybe.
Whatever the case, the boss is said to belong to an upcoming Rockman game.
More details to follow.
UPDATE: Further postings on 2ch seem to indicate the game that the boss correlates to is undetermined.
Thanks for the scan Tim.
