Update:

Ken-ichiro Imaizumi, a senior producer at Metal Gear series developer Kojima Productions, says that the number "2" in the in the sizzle reel from the 2015 Taipei Games Show is not teasing a Metal Gear Rising sequel.

Imaizumi said he doesn't know what the number "2" stands for. "Sounds like it just a countdown number '2.' It's [Sony Computer Entertainment] made trailer."

The original story follows below:

It looks like Metal Gear Rising: Revengence, the character action game spun off from the Metal Gear series, might be getting a sequel.

The news comes from the 2015 Taipei Game Show, where during a sizzle reel of PlayStation 4 games, the number two, stylized like the Metal Gear Rising logo, appeared for only a second. It appeared specifically during a short clip showing off the PS4 exclusive third-person shooter The Order: 1886. As the character was counting down, the Rising tease flashed on the screen when she said two. You can find the exact moment in this Twitch steam at the 2:46:33 mark.

Metal Gear creator Hideo Kojima was at the show, but he didn't discuss Metal Gear Rising. However, looking at his Twitter account, Kojima has been meeting Metal Gear Rising and Bayonetta 2 developer Platinum games lately, most recently in December 14, 2014, when he met with Platinum President and CEO Tatsuya Minami.

Is it a confirmation? Far from it. It's a very subtle tease at best, but one that does seem to fit Metal Gear and Kojima's sensibility.

Metal Gear Rising: Revengence was released in 2013, and featured Raiden, the protagonist of Metal Gear Solid 2: Sons of Liberty, instead of of Snake, and fast-paced action and an innovative slicing mechanic instead of stealth. GameSpot's review gave it an 8/10.

Metal Gear Solid V: The Phantom Pain launches in 2015 for Xbox One and PlayStation 4. A PC version of the open-world game is also in the works, but Konami has not announced a release date for it.
