No, it wasn't Le Chiffre. He was killed by the money-men when he was torturing Bond. I thought he must have been the guy who Vesper had been in contact with, when she led him to Le Chiffre at the torture place. And then she was going to give the money to him that she'd withdrawn from the bank account when she did the disappearing act.
Presumably somebody between Mr White, the Italian bloke who played Pazzi in Hannibal who Bond zapped when he was in recuperation (can't remember his name, began with M), and whoever the main baddie is who Bond is going to meet in the next film.
