Nakayama said half of their games that go on sale this year will be for Nintendo 3DS. So far, Marvelous has four games slated for release this year: Rune Factory Oceans, Night of the Sacrifice, Half-Minute Hero Second, and the only 3DS game in their current lineup Animal Resort: Let’s Build A Zoo.
From the quote, it is not clear if Nakayama meant calendar year (i.e. Jan. to Dec.) or fiscal year (April 2011 – March 2012). Going by calendar year, Marvelous would have to release at least two more 3DS games to stick with Nakayama’s plan. A Harvest Moon title for the Nintendo 3DS has also been announced, but it does not have a release window.
