Hideo Kojima joined an E3-hosted roundtable and Q&A session today, and he fielded questions from attendees regarding the recently announced Zone of the Enders 2 and Metal Gear Solid: Substance. The most interesting bit of information that the series creator revealed was that he and his team were currently researching the technology required to take the Metal Gear Solid series online. No specifics as to how the game would work were given, and Kojima stated that the team wouldn't begin to think in those directions until their technology-related research was completed. Whether this will manifest as a full online game, or as a series of complimentary features for the next single-player installment in the series, is not yet known. We'll have more on this as it develops.
