Mark Karpeles interviewed in a chat, using the handle MagicalTux:
[12:01] <MagicalTux> ... any BTC I own personally were on MtGox
[12:02] <JonWickedFire> How much did you lose yourself?
[12:04] <MagicalTux> Well, technically speaking it's not "lost" just
yet, just temporarily unavailable

Heh... whatever he's talking about here makes far more sense than saying
that 744,000 bitcoins were stolen from cold storage, over a term of
years, without anyone noticing. I don't think we've heard the true story
yet.
