Maybe I misunderstood but it seems like the author was upset because Nintendo didn't reveal their line-up for E3 ... Has Nintendo ever revealed their line-up for E3?
E3 is the most important press event in the industry because it is the only time you have access to a large portion of people from the mainstream media to look at your stuff; it is the only time you can get your game hyped in a major news paper months before your game is for sale. Nintendo knows that after a reporter from the nowhere-times sits through a boring 2 hour conference from Sony about how slightly better graphics are amazingly interesting, when Nintendo shows of a video of an unexpected game and gets the crowd cheering the second they realize what they're seeing, something special has happened ( http://youtube.com/watch?v=rsrcACV3Fjk ) ...
Of course Nintendo could release screenshots months in advance and get the audience asking whether they see better specular highlighting than the previous version ...
