The FAQ may be badly worded but the fact the extension applies to FBARs has been regularly reported by CCH, BNA, etc. and a senior IRS official has directly confirmed it with my firm. People can take it or leave it. If it were me and I hadn't filed I would rather take the chance to get it in by October 15, referring to the IRS announcement, rather than do nothing.
And the 2010 extension applies for signatories with no financial interest or has to do with comingled funds. The large majority of people here, I would simply guess, are needing to file an FBAR for their personal/joint bank accounts, so neither of the exceptions would apply.
