As far as anybody can tell they haven't fixed their software bugs, Gregory Maxwell wrote about that yesterday[0]. The gist is that they haven't fixed incredibly easy bugs, and are still spending unconfirmed transactions that they were warned about months ago (in this case not withdrawals, just automated housekeeping transactions).
I'm on the fence weather they will reopen their own withdrawls or not, they don't seem to be in too much of a hurry. From them moving to a virtual office[1][2] it sounds like they were threatened or some other physical incident arose that made it necessary for them to mask their location. We probably won't ever know about that, but it's not a long stretch to imagine somebody with a lot of money there could do something stupid.

There have to be some colourful people with very large deposits at Mt. Gox.
Past that, we can't assume much about the situation until they tell us what the status is. Hopefully it'll resolve this week and we can all move on from it. Lessons learned.
I don't have funds in MtGox, but I really wish they could at least make everyone whole using profits(that hopefully were eventually moved into fiat) before shutting down. I'm mildly impacted in that my day-trading has been stalled since MtGox drama has prevented the monthly'ish high swings of coin prices. But I know that's nothing compared to funds mtgox account holders stand to lose in this. However, I'm not sure I have the same sympathy for these folks[1].
