Boo!
I hadn't noticed it at first, but Nintendo has indeed changed their logo. It's only a colour change, but still. I never noticed until reading that Kotaku article. And looking over my Wii games, the logo isn't in red anymore on more recent titles, Like Super Mario Galaxy.
I know it's not a huge deal, but grey IS boring. Nintendo is red; it's always been that way. Just like Sega is blue. I don't like when established companies changes their logo. I am glad it was only a colour change, but I still don't like it. It looks much better in red.
