"He could have ended the bk then and we could have been sitting on our escrow markers post bk closure today and get paid now. "
I don't have answers to all other questions you have in your post but it is my opinion that the reason for the delay is to let JPMC continue to make money off our backs by continuing to delay payments for our assets for as long as possible... in effect they are making money 'for free' because they still are holding all the Capital that they otherwise needed to have paid to us WaMu Escrow holders for the Assets.
