mtgox coins are most likely mixed a hundred times and split into very small wallets. and surely a certain % of the coins are dumped.
Massive amounts of them coins have been dumped since they was stolen, probably one of the reasons the price has come to less than a quarter of the price since then. I do wonder how much they have left though, because they must have quite a stack still the horrible little thieves, so so much stolen funds never to be returned no wonder we lost a lot of people who was around for that.
the dump of gox coins definitely had a huge negative impact on the price but the current price is also the result of merchants getting their sales converted to fiat.
