Nintendo president Satoru Iwata has responded to criticisms of the frequency at which it is releasing Mario games.
In an interview with Kotaku Iwata said Nintendo has a history of releasing one Mario title per system. Although it is likely to continue with this trend, the decision ultimately rests with series creator Shigeru Miyamoto.
"We only create a New Super Mario Bros. title one per platform," Iwata said.
"I think we'll probably go ahead and continue at that pace. That being said, that's probably [Mario creator Shigeru] Miyamoto's choice, so I can't give you a 100% guarantee that that's the pace we'll continue at."
New Super Mario Bros. 2 was released on the Nintendo 3DS last week and New Super Mario Bros. U is expected to launch alongside the Wii U later this year. Iwata said he wasn't worried about the close proximity of these since they offer incomparable experiences.
"These are two very unique and separate titles," he said. "We have a Mario you can play in the palm of your hand and a Mario you can play seated in front of your TV."
"I believe the two titles are unique enough that I wouldn't say that I'm super-worried that people are going to be confused."
Earlier this month sources speaking to CVG told us the Wii U release date has been delayed to December across Europe due to manufacturing hiccups.
