Unanswered: will his lenders go after him for fraud if he files BK? By him making #Twitter fail so badly so quickly, I think they should be able to prove it in civil court.
Also, I wonder whether they made him put up Tesla and / or SpaceX ownership as collateral. If they only relied on Twitter assets, they'll be lucky to get 50% (and I'd guess 20% is more likely, as most of the company's value was as "a going concern").
