If it's actually using the splitBigOutputs() function they should end up in 30k different addresses holding less than 10 BTC each.
It seems that exactly this happened. The addresses that already are down to below 10 BTC have stopped splitting. Others that still contain more are continuing to split. I think this implies pretty strongly that Gox still controls the coins. The good thing is that they still exist. That bad thing is that they chose to lie about it so they probably weren't planning on returning them..
