He could have dumped already if that was his plan. Now, if you mean run prices up and dump at higher prices, that is another question entirely. However, it's pretty clear he is not dumping ASAP like many seemed to claim he would. He could have already done a HF to instant power downs to select accounts only if he wanted, but he hasn't. Not saying I would buy into the FUD at the current price, but it's clear that the fears were already overblown. It all comes down to how much Sun wants to put into this to make steem go up.
