Perhaps the biggest announcement of the summit was....

I was a little disappointed at the lack of Golden Sun info, but I'm guessing that'll be a DS holiday title.

I think you are right that the silence regarding holiday or new releases means Nintendo have something big in store. I also think it's a good approach getting core titles like Sin and Punishment, Monster Hunter Tri, Galaxy 2 and Metroid out the way before they announce the next big thing. I think Xenoblade, The Last Story and Zelda will be the big focus at E3 this year, with a couple of new, smaller titles too. That being said, I'd be very surprised if The Last Story made it out of Japan in 2010, I'm more hopeful for Xenoblade.

But yeah... I think Nintendo are prepping a Wii Relax/Zelda combo for the holidays. Wii Relax to expand the userbase and sell the vitality sensor, and Zelda to push motion plus and satisfy the 'core' market.
