XCOM: Enemy Within Listing Spotted, Unveiling on August 21st

Computer and Videogames recently spotted some listings for XCOM: Enemy Within on the South Korean Game Rating Board (GRB). There are listings for a PC version, an Xbox 360 version and a PlayStation 3 version, making this a current-gen title, if not even an expansion pack. And the second hypothesis seems fairly credible, considering some "XCOM EW" listings have apparead in Steam's Database, under the XCOM: Enemy Unknown header.

Either way, it shouldn't take long to discover what exactly we're talking about, given published 2K told VG247 they'd announce it properly on August 21, which, incidentally, is the opening day for GamesCom. (Thanks, NeoGAF)
