Metal Gear Solid creator Hideo Kojima has teased some sort of PlayStation 4-related news to be revealed tomorrow.
On Twitter, Kojima first promised "important news" on SpikeTV on Thursday.
In a follow-up tweet, he described the news as "a shocking PS4 related announcement that will blow your mind".
The news may be something to do with the PlayStation exclusive content for Metal Gear Solid: Ground Zeroes.
Metal Gear Solid 5: Ground Zeroes is coming in northern spring 2014 as a separate prologue to Metal Gear Solid 5: The Phantom Pain, which has not been dated.
Both are coming to PS3, PS4, Xbox 360 and Xbox One.
Kojima has been on a press junket in the US for the past few days, so presumably we can expect plenty of new MGS 5 news sometime over the next few days as coverage emerges from under embargo (and out of dictaphones).
