Nintendo pulled a fast one on Japan today. They announced that before the end of this year Nintendo will be releasing a new DSi, the specs will remain exactly the same with the exception of its screen size.
The screen size will increase from the current 3.25 inches to 4 inches and will retail for the same price as the current DSi models. Nintendo is still determining whether it will release it outside of Japan.
I don’t have a DSi but it seems like kind of a bummer for people who may have recently purchased a DSi. Of course worse comes to worse you could always just trade in your DSi and pay the difference if it ever does leave Japan.
Note: Picture is of the old Nintendo DSi, there has not been any images released by Nintendo at this point.
