I'm pretty sure I saw the EE in theaters, and this will be the EEE. The short scene between Elrond and Bilbo was kind of nice, but the rest was totally unnecessary.
The nice thing about the LOTR EE was the extra bits and pieces that were largely based on things from the books that otherwise don't have a solid place in the films. I guess for the Hobbit EE it'll just be extra dwarven buffoonery that even the extended, three-film version doesn't have room for.
