A sequel to Plants vs. Zombies may be revealed soon. PopCap Games is teasing an announcement for the series.

Several gaming publications like PC Gamer received a "Save the Date" from PopCap today. It's an image of a zombie clutching a sign that says "August 2, 2010." The initials "S.F." are written in the corner next to a drawing of a bridge. Maybe they're planning a press event in San Francisco on that day?

PvZ is a tower defense game in which the player uses different species of plants to repel undead invaders. It has appeared on the PC, Mac, iPhone, and iPad.
