If you haven't noticed with all the flame against Nintendo that IGN had few months ago. Apparently Nintendo listened to them, and stepped. They put effort in SMG2. The effort I am talking about is Orchestral music over MIDI music. They had originally planned MIDI as you can see from the E3 trailer, but taking press's feedback, they added orchestral music. Clearly not lazy.
People have been talking a lot about the Metroid: Other M delay. I think there were two main reasons for such a delay.
1. It would be too close of a release to Sin and Punishment 2 and Super Mario Galaxy. Nintendo's own competition would be themselves.
2. Voice-Acting. If you read the previews of many reviewers, you would have noticed them saying something about how terrible the voice acting in the build was. Nintendo realized this, and decided to make it better while giving the game a slight delay.
This is purely a thought, but I think the voice acting, some fine-tuning and polish are the main reasons why Nintendo delayed Metroid: Other M. I respect them for this. Personally, I would not mind AT ALL if Zelda was pushed to next year in holiday-time, if the time was used to add voice-acting, more polish, more features, extras and all. I want a perfect Zelda experience, because you only get to experience it for the first time, once. I hope Nintendo continue to listen to feedback and incorporate it in to all their games. It just makes their game a leap beyond the competition.
