Metal Gear Solid 5: Ground Zeroes is out in December for PC?

Multiple Russian sites are reporting that Hideo Kojima himself revealed the December 18 date to fans at the convention.

Announcing a PC release date at a Russian game convention would make sense, considering the country has one of the largest PC communities in Europe and the world. And we were expecting the PC port to release this year anyway, and not be delayed to 2015.
