I'm hopeful that MtGox will sort out their problems, but I don't know whether it will be days, weeks or months before they can honour everyone's bitcoin withdrawals.

BTC on MtGox are only worth 3/4 of BTC elsewhere right now, and the trend seems to be that it will drop more.

There is an active market of people exchanging their goxxed BTC for real BTC https://bitcointalk.org/index.php?topic=455243.
