It's easier to be psyched and hyped for something that can be anything than what is plainly in front of you. The sky is quite beautiful, but it's the possibility of aliens that hypes up a news story. Essentially, although I know where you are coming from, you are only psyched about that unknown lineup because it is unknown. And those magazines feed off of that for hyping their stories by using statements as "bigger than last E3's combined" which is purely subjective and can't be wrong or right.
What you should take from this media summit is Nintendo's commitment to release big titles throughout the entire year, have a bigger online sector, and take part in big 3rd party titles that they think are worthwhile. Even more, you should be hyped for the likes of about everything they showed because they really showed a good deal. We all can't wait for the Zelda trailer or whatever Nintendo has up their sleeves, but for now we've got some pretty amazing stuff in their own right. Mario, Metroid, Sin and Punishment 2, MH3, DQIX, Pokemon Heartgold/Soulsilver, bunch of Wiiware and DSiware titles, and DSi Xl... I'd say that's a win for the home team.
