Further Gears 2 DLC in April?

Joystiq reports that Epic Games and Microsoft has more than the previously announced Snowblind map pack on the way for Gears of War 2.

According to an "alleged Asian product page", the Gears of War 2 DLC won't stop with Snowblind, but will be followed by a pack titled Dark Corners at some time in April. There's absolutely no info on what this new DLC will offer, although rumours suggest new campaign levels are incoming.
