Speculation time to bring this thread back on track:
Will Reggie or Iwata come out first on stage at E3?
What whacky thing will Miyamoto do?
How long into the conference before Iwata flicks his lovely set of hair back?
Yes I'm getting desperate because it seems we've run out of everything else to speculate about.
Ideaman, Lherre, ShockingAlberto, please, please save us?
Reggie will start it off, make a 3DS game announcement. Hand off to Iwata, who will talk philosophy on bringing the home console experience out of the television and into your hands. Reggie takes the stage briefly for a "developer reactions" montage, then to introduce Miyamoto, who won't demo a game but will introduce Pikmin United. Reggie comes back, casually mentions that the system is the most powerful console in history or something vague like then, then introduces an unexpected but popular developer to talk about their lazy port attempt. Back to the Regginator for a
very long rundown of the extended, non-game features of the system (like universal control of all your kitchen appliances or "watch any video ever made instantly" or whatnot). Then a third party video montage.
Then rails will shift to upcoming 3DS games (and charts) for a while. After this, Reg will do a "one last thing", but it'll be a game that we kinda sorta expected but were really hoping for.
There will be no Feel Screen (electrostatic haptics) or TimeSplitters 4. I will cry.
I suspect that Miyamoto will be pretty reserved and that Iwata will barely flick, at best. The presentation will have a more "professional" feel to it with less of the silliness we're hoping for. The next day, we'll actually get a few kiloton game announcements -- let's say two for the Wii U, one for the 3DS (this one could be megaton-level, like the always lusted after FF7 remake).
tl;dr: Solid but unspectacular, saved partly by announcements afterward. It's okay, though, since Sony's conference will be a clusterfuck, and Microsoft will sort of just cruise by with some promises about their next-year hardware but not much in the way of playable next generation software.
