But it seems that is not the point. If it was, why cancel the E3 conference anyway?
Not that they can`t show vídeos of that - some sites will probably show - but, unless something changes, news will only come in the form of NDs (only thing confirmed so far).
I guess I'm reading "media presentation" differently than you are, because my take away was that it would be a livestreamed event, and that they didn't really "cancel" but repurposed their event strategy, rather than one event for both, two events. One to drive home the message they want to make to investors, and one to showcase what they are offering. I'm hoping Nintendo livestreams the media event, only time will tell.
