Do you think that just stating the coins were "LOST" is sufficient? In bitcoin world, things don't get lost, the private keys are either stolen or private keys are "Lost".

Either the coins are lost forever and we should be able to be given a list of BTC addresses that the funds should NEVER be moved from since the private keys are not in existence any more, or they worked their way into a mixer and are gone. Bitcoin is the ultimate paper trail, these answers should not be that hard to find out unless gox completely wiped their database.

Which is it? any company filing for bankruptcy has an obligation to provide details on how the coins went missing. whether stolen or "burned"

My guess is the majority went missing due to karpeles accidentally dropping a table on a database of private keys.
