Facebook Event in San Francisco on Jan. 18

World’s largest social networking service provider Facebook has scheduled a press-only event on Jan. 18, 2012, without offering the slightest hint about any announcement. The invite-only event is taking place at the restaurant 25 Lusk in San Francisco, California which similarly doesn’t offer any hints about what the company might announce.

The invitation this time around lacks any iconography that could one might infer a product category from. The lack of detail on the invite could mean an announcement related to a completed financial transaction — announcing something beforehand would run afoul of US laws.
