Insomniac Games are apparently planning to hold a Ratchet & Clank event in Los Angeles later this week.
The news come from the community lead James Stevenson that appeared on the developer's official forums earlier today, requesting that LA-based fans of the series get in touch with him via email. The post stipulates that the fans must be able to be in the Century City area at mid-afternoon on Friday – heavily suggesting that an event of some kind is being planned.
