Nintendo:
...The fact that they had technical difficulties during the Zelda showcase, where they wanted to show the Wii Motion + features didn't help either...
The new Goldeneye..I don't know. Multiplayer is out of the question for me, at least online multiplayer...
I'm not sure about the 3DS yet, I have to see it with my own eyes to fully understand it. I liked how enthusiastic they were about it and that they are really convinced of it. The new Kid Icarus game looked great. An all new and original(!!!) Metal gear and Resident Evil were awesome announcements, but I have to see the hardware first and experience what it does to me to decide.
Those were really sad. Giant Bomb said that they played it on the floor, and it was nowhere even close to as bad. Someone there said it wasn't "1:1", animation matching remote, but it was close. I think the lights fucked with the IR sensor on stage.
Is the latency horrible on any P2P shooter for you?
Giant Bomb thought the 3DS was great, and it worked really well. Indirect quote "I wasn't really sold on the DS and Wii, and those turned out really good. But I'm sold from the start on the 3DS."
The tech demo at E3 looked like MGS3[DS]. There's no telling what the real game will be.
