Kojima hinting at MGS5?

Oh Mr. Kojima, why do you do this to us? At Tuesday's Metal Gear Solid 4 press event in Tokyo's Roppongi Hills, the Kojima Productions team left those attending the event with a small audio clip that has spread like wildfire across the interenet about a possible sequel already in the works for the Metal Gear Solid franchise.

The audio clip featured a conversation between Revolver Ocelot and an unknown character, with only Ocelot's side of the conversation presented in the clip (with subtitles shown on the screen). Mark MacDonald, from 1UP.com, provided the translation of the subtitles to English: [Ocelot's voice] Yes. We just finished the press conference. Yes. Everything went according to plan. Yes. We're entering into the last phase of the mission. Do you want to execute the launch day surprise? Yes, that's right. Akihabara, New York, L.A.... Live, simultaneously throughout the world... Yes, it's under control. The VIP's are happy to participate. Yeah, that's right. That person. Yes sir, understood. So on June 12th... By the way, what should we do about "The Project?" Yes, that's correct. That man has fallen. It's about the sequel. Yes, indeed. Yes. Yes. Yeah. I see. Yes, sir. Mr. CEO.This can be taken a whole bunch of ways but the first thought to mind (as the conversation clearly states) is that of a sequel to MGS4. Although there is no telling just yet, its likely that the conversation partly refers to the planned launch events and creator Hideo Kojima's world tour, both of which were discussed at the event. I guess we are all left wondering until June 12.
