I made it to E3 yesterday from 9am to 2pm. I should've been prepared. I went to the Nintendo booth thinking, I can always get in line later for the huge Wii booth. I was wrong. When I came back to the booth at 10am, the line was already wrapped around Nintendo's entire booth. To my dismay, I never got to touch the Wii at all because I didn't stand in line when the doors opened.
I should also add that when the doors open at 9am, I've never seen so many grown men, who weren't athletes, take off in a sprint to just one booth.
I played a lot of DS, PS3, XBOX 360, PS2...but I didn't get to touch the Wii.
So back on topic: From this unfortunate experience...the Wii definitely had the edge yesterday. Despite a very impressive showing from XBOX 360 and PS3, which were both amazing, the Wii dominated...Nintendo wins.
