Haha, I did a couple of searches for old Japanese Nintendo ads, and I noticed that the logo they used (in Japan) had a longer oval shape, but the same font. America used the logo we all know and love. When Japan started adopting the American logo, I doubt the Japanese cared.
But people are seriously offended by this color change? Wow... to my knowledge, Nintendo used different colors for their logo in game intros. The most common one I saw was a white against a black backdrop. It's not even a big change.
And FYI, the best Konami logo was the one with black italics. The one they used mostly in the SNES, NES days.
