Although we've been seeing it on boxes for a while Nintendo has officially issued a statement that basically says that their iconic red logo will be changing hues to a nice gray colour. Sent to media outlets today Nintendo has said: ""For several years, a new generation of Wii and Nintendo DS games have adorned themselves with a new logo, in discrete grey. In various publications the former logo, with red lettering, can still be seen. We would like to sincerely ask you to now only use the current, gray Nintendo logo."" We'd like to point out that nothing else about the logo has changed, which is good to see..
