Microsoft have criticised Sony for their Delay to Europe of the PS3 saying that they know what it’s like to have to have to pull off a global release. They criticised the unproven technology in the PS3 (blu-ray) for holding things up.
Nintendo have not taken the opportunity to attack Sony but have instead (possibly to get at them more subtly) re-stated their plans to get the Wii released globally in the fourth quater.
I wouldn’t have predicted this situation unfolding any differently to this.
