I just watched the inventory Q&A with Chris Martin and there was some great info in there, so I'm going to extend my transcripting to these types of events too. I'm creating a separate thread because this could potentially continue past the hobbit runs.
Please note: I am paraphrasing here. Anything said here is coming through my interpretation of what was said, and is subject to being corrected, so don't take this as the final word.
If anyone who was present has any additions or corrections, feel free to post.
