(Kiskaloo) agreed that the 787 battery issues are currently being investigated by NTSB and JTSB, the implication in your post is that Boeing (and the subs) are confident that their fix will be approved and the bird will fly - Regardless of any subsequent findings by the above mentioned agencies?
I expect the regulatory agencies to approve the 787's return to revenue service with the current suite of modifications made.
That being said, once the investigative agencies do identify a root cause, I fully expect additional Airworthiness Directives will be issued to address them.

Apart from my concern about the Boeing/FAA/NTSB/JTSB not finding the source of the electrical problems, was it the FAA who certified the original electrical system as safe? If so, am I to trust them that they've properly assessed the new fixes as safe this time?
After JL8 and before NH692, the FAA announced they planned to perform a comprehensive review of the 787's electrical system and their certification of it.
