Metal Gear Solid creator Hideo Kojima has jumped aboard the PlayStation 4 hype train and is inviting you to do the same. Tonight during Spike TV's PlayStation 4 All Access event, "there'll be a shocking PS4 related announcement that will blow your mind," Kojima said on Twitter.

What could it be? Is he speaking about something Metal Gear Solid related? After all, Kojima did tease exclusive PlayStation content for Ground Zeroes. Perhaps it's the long-awaited return of Zone of the Enders? Nah, probably not. Maybe it has nothing to do with one of his franchises and is just something new from Sony. Uncharted 4? The Last Guardian?

What do you think will be revealed tonight at the PS4 All Access event? We know something's big enough to take Sony exec Shuhei Yoshida by surprise. Be sure to check back here at GameRevolution for all the news coming out of the event.
