Super Mario 64x4 may not be the first plumbing platformer to appear on the Nintendo DS according to veteran designer Shigeru Miyamoto, with a second, unnamed Mario title the more likely candidate. Speaking during E3 in an interviewed published by GameSpy this week, Miyamoto admits "there is another Mario game that we are working on for the DS," before saying "I think that will be the next Mario game to come out."
Whether the popular developer is referring to "NEW Super Mario Bros.", which was trailed in video form at E3 and showed a scaleable full-screen Mario stomping around 80s era Mario Bros. level design, is impossible to say, but it's quite feasible that Miyamoto is referring to an entirely different Mario title. His answer came in response to a question asking which format the next new Mario adventure would appear on. "It may end up on DS," Miyamoto told GameSpy. "You may have seen Mario 64x4 here, but there is another Mario game that we are working on for the DS that is best suited for that system."
