Details are old, but this is what I've been getting my info from, as well as discussions with you. I'm sure things have changed a bit, as Ocean basically found his aesthetic after these posts (ie these are pre-rework statements on the whole), so everything needs to be seasoned with a lot of salt. I think some things like the description of BTW will have changed - I don't think older, wiser Ocean will even toy with that concept, unless it is a major part of the plot.
