MASSIVE: The future of networked multiplayer games is a conference to attend if you're around LA/Irvine on April 20th:

MASSIVE will engage 25 speakers and approximately 80 registrants from industry and academia in a dialog about the future design, technical and cultural challenges presented by massively multiplayer games, current and future research agendas from both industry and academia, and case studies and future models for industry academia collaboration.

And of course, Julian will talk about the most important question related to mobile gaming: "How can mobile games become more than just Tetris on a phone?".
