Syphon Filter 4 accidentally leaked by Sony?

The forums of Giantbomb as well as GameTrailers are claiming that Sony’s US PS website had posted information regarding a new Syphon Filter title, Syphon Filter 4 before quickly taking it down.

Apparently, the game is in development at SCE’s London studio and is being made using a completely new engine. The game is slated to release in Q4 2012, the post claimed.

They’ve also posted a rather shady looking logo of the game, which you can see above.

We’ll send Sony an email and await an official word. For now, take this with a huge mouthful of salt.
