I wonder, once the BD specs are all complete and everything is ready for WB to author, have they done most of the up front work as to minimize the up front work for these titles? It's likely that the encodes are the same as the HD-DVD versions, so I'm assuming they have all of the assets ready to author the discs. They're probably just waiting on the spec to get finalized.
They may already have them authored to the current unapproved spec with the hopes that the features they're using don't change between now and the actual approve date. If that's the case, they could be ready the second the spec is approved and testing indicates everything they've authored works.
Nah. That's scenario would entail doing work that might get nullified by a changing format.
In any case, I wonder how long, after the BD+ standard is set, it will take them to actually start releasing titles.
