So a lot of the D.I.C.E. keynotes were put online via the Variety Youtube channel. Pretty interesting stuff getting to hear what developers think on various subjects and were the industry is going.
I don't recall any Japanese developers doing any keynotes this a year but its still pretty interesting stuff.
Valve Founder Gabe Newell "A view in the next step of the industry"
Sledgehammer Game's David Schofield "The art of Inspiration"
Telltale's Dan Conners on "Episodic Gaming"
Thatgamecompany's Jenpova Chen "Theories Behind Journey"
Quantic Dream's David Cage "The Peter Pan Syndrome: The Industry that refused to Grow up"
Microsoft Studios/343 Industries Kiki Wolfkill and Frank O'Conner "Changing the universe- three for three".
