It makes perfect sense. Before E3 starts, before the press conferences, before the keynotes, and before the doors open they will have 2 events. First a meeting with retailers, talking about their strategy and their games and hardware. Getting the distributors and retail giants excited.
The second event is for the press. It's a hands on booth with every Wii U game they are working on. Mario Kart, Smash Bros, Pikmin, Wonderful 101, 3D Mario are all going to be playable. All this before Sony and Microsoft even step in the door that day.
Then the press will go post to their blogs and such about what they played.
So purebeast who doesn't have a fucking clue? It's you.
Every single person who knows they aren't doing a keynote found out online. Those same people will find out on day one of E3 what games were playable, how they were, what will be shipping and when. They will find out from the same sources that said "No Nintendo Keynote speech at E3".
They aren't rumors...
God you guys are ridiculous. Nintendo confirmed they are playable. Yeah, you will be able to play those games on day one of E3. Some of them are very, very far into development. How can you confirm a playable game and you say it's a rumor?
