We are still discussing this with our legal counsel actually, however filing the theft details pre-emptively from our side may make things easier and faster, and may protect us and our other customers too.

You can bet if I realised that amount of funds had gone missing from my account I'd be waking Mark up in the middle of the might. It's also reasonable to assume that Mark immediately went about securing evidence once informed of the event. I'm not sure why you think the time is especially significant given how many people start work early even on Saturdays.
If money had been stolen from your bank account, it would be the bank who notified the authorities (after all, they have the transaction records). In this case, it should probably be MtGox which files the initial report. There is zero reason to believe that attempted thefts will not continue if intruders know they will likely not be discovered and prosecuted.
