This was a weird topic last year and it's a weird topic this year.
Press conferences did Nintendo no good when launching the 3DS and the Wii U. In fact, I think we can associate more failures with press conferences than we can with winners. Remember Sony's disastrous conference where they revealed the price of the PS3? Or Microsoft's unveiling of the Xbox One?
Conferences don't enhance the message. It doesn't mean they're bad or not useful. It just means that we're approaching this conversation from the point of "If Nintendo has a press conference, they will do better as a company." We think that press conferences are the golden ticket to mainstream recognition and appreciation. But that's not true, and it really never has been true.
The near-mythical, highly sought after, mainstream market is attracted to the right message. Marketing is far more than PR and Advertising. It's more than just events. It's in the product design, it's in the objective, it's in figuring out who the product is for and who will be the most receptive to a message. If the message is bad, the way you deliver it is not going to help.
Look back to last year's E3 Direct. Was there any info in that direct that you think would have been enhanced by a conference? By having journalists in seats, live blogging to their highly engaged constituents? Was the problem channel obscurity? It really wasn't, and deep down I think everyone (maybe except Nintendo) knows that it wasn't.
Last year, all of the outlets wrote the same articles they do every year about the message Nintendo presented to them. They went to the show floor and wrote hands on impressions of all the games Nintendo had lined up, just like every other year. Press-Kits with trailers and assets were disseminated to all the major players, and all of them decided which they wanted to put up and which they did not. Very little actually changed. It's just that Nintendo's message is not effective. Their product, their lineup, and their entire image isn't catching on this time. There's a multitude of reasons for this that we could go on forever about, but that's the issue. All this talk of trying to explain "why" Nintendo is going digital only with their media is pretty frivolous. If Nintendo announced a fully 3D console with the best graphics money could buy on an E3 Direct, you can bet your ass that would be all over the most important outlets, trending on twitter, and showing up on the evening news.
It's all about the message, not about the delivery. That's what makes this conversation so weird. We're trying to associate one thing (Nintendo doing bad) with another (Nintendo deciding to not do press conferences), when the two aren't necessarily related.
