Organizers for the Virtual Worlds Forum Europe 2008 announced that Jagex CEo Geoff Iddison will deliver a keynote at the event, as will Mel Guymon, Google's Lively product manager and head of 3D operations.

Scheduled to take place during October 6th to 8th, the conference will be held in London at urban venue The Bridge. In addition to featuring several dozen speakers representing the virtual worlds industry, the expo will have developer booths, technology and virtual world demos, and hands-on workshops.

Though Iddison hasn't yet revealed the topic for his keynote, it's likely he'll mention RuneScape, Jagex's Java-based MMORPG and flagship title claiming 5.4 million active users. The company recently launched a beta for RuneScape HD, a version of the game featuring higher definition graphics.
