Batman 3 announcement coming late 2010 / early 2011?

Everyone wants to know when we’ll get that official Batman 3 announcement.  Many of you voted for late 2010 (November or December) in the poll I put up last week.  Today a “friend” of BOF reports that an official announcement will come right before the end of 2010, or early in 2011.  With filming said to begin around March/April of next year, I think an announcement then would make the most sense. They’ll want to announce the title and cast before filming begins so that the information doesn’t leak out while they’re on set.
