Thanks to Brad in the forum for pointing out that John Romero seems to be missing on the Australian Game Developers Conference webpage. He was one of the major speakers scheduled, and was to talk about the future of mobile gaming at the conference. It looks like he won't be visiting our shores seeing as his details have been removed on the main page, along with his slot in the schedule. ** Unfortunately due to an urgent family matter, he has had to withdraw (thanks Brain for the confirmation).
