Andriasang has listed the questions asked to Hideo Kojima during the new Kojima Productions podcast and the answers he gave, all of them being simple yes/no questions. Amongst them is a denial that the studio is working on a NGP-port of Metal Gear Solid 4: Guns of the Patriots, or that they will be at E3 to showcase Metal Gear Solid 5. While we can expect Konami to bring Metal Gear Solid: Rising to E3, Kojima himself will not - according to the podcast - show up at Microsoft's press conference this time around.
Something big is planned for the 25th anniversary of the Metal Gear-series next year, though.
If you had Metal Gear Solid 5 on your "games I want to see announced at E3"-list, you can scratch that one now. Sorry, guys.
