Mashable is reporting that Facebook’s iPad app will launch on 10/4 along with the widely rumored El Cinco announcement. Second in legend only to a chupacabra-taloned sasquatch (chupasquatch?), rumors of the app have been flying around for a while now – a few months ago code for the app surfaced, and people started posting screenshots. And yesterday, an ex-Facebook engineer fired off a disgruntled blog post saying that the app had been nearly complete since January of this year.

If the Facebook iPad app actually does get released, we’ll file it alongside Guns n’ Roses “Chinese Democracy” as things that we never thought would actually get here. Still waiting on widespread adoption of the metric system, the popularity of soccer, and Chris O’Donnell becoming a big movie star.
