I agree...Outside of Valkyrie Profile Silmeria, my most anticipated games are mostly Nintendo ones. It doesn't get any better than Super Paper Mario (THE game of the show, thus far) Kirby DS and Yoshi's Island 2 (and just the mention of a new Fire Emblem is enough to get my ears perked up). And this is without seeing anything of GC Kirby and the new Smash Brothers or considering New SMB hits in a couple days.
One I wasn't expecting to be interested in was Metroid Prime 3 (wasn't too fond of the first one), but the realization of how the controller was going to function with it has me looking for more info on it.
And I think SNK and Nintendo make a nice pair...Metal Slug Anthology for Wii and a new Cardfighters Clash for the DS (maybe as good a surprise as SPM). That's just the tip of the 3rd party DS iceberg: Megaman ZX, Magical Vacation, FF3, Cooking Mama and a new Metrovania.
It's scary, comparing Nintendo at this time last year and this year...Didn't think they'd be headlining one of the strongest E3's I've ever seen.
