Yea, Mt. Gox was one of those places that even non-crypto currency persons may have come across or at least heard of. Don't think they'll be able to make a come back with all the negative press that came out on them.
If a third party were to buy the company/site/name then they could do something good with it.
They would need to prove their security, competence and internal controls but it could happen.
In the days before it was "public" that gox had failed there was a leaked document that said one of GOX's assets was it massive user base, KYC'ed customer base and trading platform.
