Here's more detailed speculation on MtGox's solvency: "The good news is that MtGox made huge bitcoin profits over its lifetime, which are more than enough to cover the holes in operating capital due to seized accounts and the lawsuit filed by Coinlab. The bad news is that no one knows if MtGox kept the bitcoin, or traded it for fiat." http://blog.standardcrypto.com/2013/09/07/who-will-buy-mtgox...
