Those of us who saw WOZ very early saw an incomplete game that COMPLETELY blossomed well into the production run with code additions. Bear in mind that due to the licensing being tied to the release of the 3rd Hobbit film, we are NOT seeing a completed game - I would presume that anything using features/clips/audio from Film #3 is probably not in the code version we are seeing in Chicago.
Just remember how well WOZ completely met (and exceeded) its potential with Code Release 3.0 - which was a good 6-8 months after the first games went out.
A select few received WOZ and SOLD IT well before V 3.0 - they waited a year for it and then could not wait long enough to see the final version before growing impatient and dumping it. Their loss. I feel like people who did this were foolish.
Hobbit will be fine.
