Pikmin and Animal Crossing are proof from the last 5 years that Nintendo can still come up with great original games, and I care a lot more about games than I do about "IP's" (I never want to see Pikmin Golf, for example.)
You guys hope for playable Smash Bros., I hope for playable AC or Pikmin on the Wii. Hey, I'd even take Pikmin on the DS. Both of those games looked totally dumb until I played them. I hope to see something at E3 that I think is equally ridiculous on first blush but turns out to be one of my favorites after I play it for a while.
Now, Nintendogs is not the kind of thing I'm talking about at all, though I did enjoy it for a while until I had 3 superdogs and nothing to do with them except let them grow flea colonies. I'm too old for a Tamagotchi experience that just goes on forever, requiring constant effort with no additional return once you've gotten all the medals. If I had kids, they'd be too old for that sort of thing too. But I'm ready to be impressed or disappointed by Wii Music or something I don't see coming at all... the way Nintendogs blindsided me and everyone else. I guess it all comes down to what Miyamoto's been up to when not working on Nintendo's marquee titles. Gardening begat Pikmin and real life dogs begat Nintendogs. Let's hope it's not Wii Colonoscopii.
Anyway, keep in mind that as far as Nintendo is concerned, E3 is now "an hour-long press conference in a big hotel room". There's not going to be anyone like Miyamoto running out on stage with a prop shield while the orchestra swells. Reggie is not going to come out yelling about how he's going to kick ass and take names.
E3 is going to be a bunch of guys in suits (Reggie and Iwata probably among them, maybe even Miyamoto since the media is still as high on the Wii as consumers are, and will eat up another reiteration of its origin) talking to a hundred or two journalists, mostly from print and broadcast media plus a handful of really big web outlets. They will be standing in front of some folding tables and have a video projector, and at some point someone will probably clear his throat nervously and go, "Um, lights, please?"
It's not going to be Nintendo as rock stars. It's going to be Nintendo as TV network execs. It's not going to be Nintendo trying to win over gamers who are already loyal to them. It's going to be Nintendo looking out for their stock price. This is what we have to look forward to in a couple weeks. For the rock star routine, if we get it at all, we'll have to wait till PAX, E4all or TGS.
E3 as a focal point of interest for (most) gamers is dead.
