Nintendo have registered the domain SuperMario4.com, GoNintendo reports.
Back in January, Nintendo CEO Satoru Iwata confirmed plans that the company was to develop a “totally new side-scrolling action Super Mario in 2D”.
This was stated as set for Nintendo 3DS, and due to launch within the new fiscal year (between April 1st 2012 – March 31st 2013).
The registered domain currently leads back to Nintendo.com.
Presumably, if it is indeed intended for use with such a future release, we’ll find out more at E3 2012 in June.
