In just under a month, more than 22,000 people directly associated with the video games and electronic entertainment industry will descend upon San Francisco's Moscone Center for the 2013 Game Developers Conference (GDC).
A professionals-only event in its 27th year, GCD is a forum for learning, inspiration, and networking those who create game software for computer, console, handheld, smartphone, tablet, mobile, and online games. In short, it's a big deal.
If no one from Nintendo is proposing topics, they're not going to get any speaking time.
One reason why I say it lays on both parties, but to your point it is more on Nintendo than anything...sad to say that...
