The manipulator is nothing but early adopters trying to cash out a little. I doubt this paradigm will change.
It is the way that it goes down that is what appears to be manipulation.
Large walls set up that then fall just as it is going down.
Early adopters are not sitting on $100k to put up walls while also selling $100k worth of BTC.
Those walls are from MTGOX themselves. with zero auditing or regulation they are free to do whatever they want on their own exchange. They answer to no one. They can easily create/remove/buy/sell 100k orders at the drop of the hat.
