OMG, I just read this on the Wii news channel, I don't think there's much to worry about, with games like Kirby and Mario, not to mention SSBB and Pokemon D/P and BR, there isn't anything "dark" coming in the near future, the only games that are a little violent coming out is MP3 and Project H.A.M.M.E.R. The more melancholic aspect of TP was of course a little grim comparing to its more whimsical predecessors, but i think Miyamoto is taking it a little too hard with the few more mature games coming out for the Wii.
