Not mentioned in the OP but there was also news out today that hedge funds are buying up Mt.Gox creditor claims.

[+] Yes, you can sell 1 BTC without meaningful price impact, but you can't sell 200k BTC without meaningful price impact, so it is not liquid by the standards of hedge funds.

But the bankrupt entity holds 200k odd Bitcoins, and that changes things a lot. I wouldn't make this trade even at an 85% discount to face value, because I think there's a significant likelihood that BTC goes to zero, and so would not buy it and especially would not buy it with embedded leverage.
