Hideo Kojima, the mind behind the Metal Gear franchise and Zone of the Enders, has tweeted to say that gamers should expect a "shocking" announcement tomorrow, which is related to the PS4.
The tweet was in relation to the PS4 All-Access launch coverage that's being put on by Spike TV. Kojima's tweet read: "'SPIKE TV' is one of the most popular cable TV channels in US. There'll be a shocking PS4 related announcement that will blow your mind."
Geoff Keighley, who is hosting the coverage, posted up a picture of himself and Kojima standing in front of a Metal Gear Solid V poster, while also then retweeting Kojima's tweet.
There are rumours that this could be confirmation of PlayStation exclusive content with Metal Gear Solid V: The Phantom Pain, but this is of course, just conjecture.
Be sure to check back tomorrow to find out exactly what PS4 announcement Kojima was talking about.
