Lord of the Rings Trilogy Extended Edition on Blu-Ray?

According to Collider, the extended edition of The Lord of the Rings trilogy could come next year with additional features. In a conversation with Peter Jackson:

He told me the first editions to hit Blu-ray are going to be the theatrical versions and a year later we’d get the extended editions. The only good news is he told me the studio has started talking to him about doing some new extras for the Blu-ray extended editions. No word on exactly what the new stuff might be.
