Gaming journalist Geoff Keighley has conducted an interview with the elusive Joakim Mogren, which will be aired tonight on GTTV. It doesn't exactly make things any less mysterious. Keighley said he saw some new photos, that this was a weird interview and that Joakim wasn't Hideo Kojima. But when someone asked wether this meant it was not a Metal Gear game, Keighley stated there is 'definitely still a chance' this is in fact Metal Gear related after all.
Update Photo of (supposedly) Joakim Mogren added.
