Maybe by doing it in ND, they can focus on software exclusively and not lame guest appearances or to talk about ESPN and other non-game related topics for like 45 minutes.
However, my logic would tell me that a big, over-the-top event would attract more watchers than smaller, more modest and split in parts showing. I mean, i've never seen a nintendo direct in my life but I have watched just about every nintendo E3 conference since the Wii was announced.
