I'm not sure exactly how the story goes, but didn't the guy who stole it have some vendetta against them? I heard he was upset that all the 'real physics' were scripted sequences that happened regardless of what was around them, etc...big stuff like that. They may be doing the game RIGHT, or re-doing a lot in the name of cheat prevention...and/or, it also just was not ready. From the blog, it didn't sound like THAT particular guy was involved.
