On Nintendo`s side, yes, they are the same. But doesn`t mean the way you present your content is the same.
If you watch just the first 5-7 minutes of 2012`s E3 conference you`ll understand how a press conference differs from a ND - let´s see what a Digital Event is all about, too.
In a ND everything is recorded and Iwata can`t always excite people. And it`s not just him. Even Reggie acts differently during NDs from when he`s on stage.
NDs are more laidback, if you will. A press conference is more about creating excitement and doing crazy things that come out in a more natural way - again, watch the first minutes of E3 2012 and you`ll see.
But enough of philosophy! :D
To me, it`s always been like comparing a band live show with watching that same show, at home, on a DVD.
There`s just no beating a live performance.
