I can see them opening up with the 3DS, then dwell into the Wii's library, then hit us hard with an announcement of the Cafe.
Close to what I'm expecting. I'd say we'll get hit with DS & Wii information (as they're the oldest and Nintendo always likes to start off with sales figures), then 3DS, then Café.
If I were Nintendo, I'd totally talk about the 3DS, then tell everyone "Oh, you can download demos and such right now.", then thank everyone for coming, walk off the stage, bring up the house lights... show's over...
...Then, Miyamoto peeks his head around the corner.
...a few seconds later, Iwata peeks around the corner - says something like "Yeah, they're still out there."
...Reggie comes out..."What are you all still doing here?"
...unpaid intern (me) goes up to Reggie and whispers something in his ear.
..."Oh! You guys think you're ready to hear about Project Café, eh?"
After some more teasing, the house lights go down and BLAM - video of Café and shiznit.
For once, I am actually glad Nintendo doesn't have anything to boast in terms of sales. Maybe it'll translate into cleaner show.
Nintendo still has plenty to brag about in the sales area. And, besides, even in the GameCube area, they still talked about sales. Because E3 isn't just for you and I - it's for press, investors and retailers. These guys actually care about sales.
