If the DAO hack gets laundered through XMR, it will establish a major precedent, and XMR will subsequently attract vast funds, as well as intense political pressure.  Expect huge volatility, along with a massive long term upward price pressure in that case.

Personally, I would not choose XMR if I were the DAO hacker, except as a long term investment.  I would move about half of my value into XMR cold storage, mix the rest as btc, and buy stolen gold and shelf-stable drugs on AlphaBay with BTC.
