Since they don't seem to be here, and since it seems weird to me that Tux would only do this on IRC and not more public with a bigger announcement... I call BS.
Wtf. Black helicopters much?

I was there.
First the .4242 amount was named by non-mtgox parties (I didn't witness this myself, but talked to the people after who did). Second the exact value of the txn and destination address were announced by mtgox a long time (probably 45 minutes?) before my node saw the flooded transaction. Apparently MagicalTux had issues getting connections up to a pre .23 wallet.
I consider this sufficient evidence that mtgox still controls that bitcoin.
