As of now? 4-5% of supply in the hands of these hackers and the code of the TheDAO exposed as terribly insecure and fubarred. ETH could seriously go sub-0.01 imho.
The worst is yet to come. Vitalic has switched the DAO to use Proof of Vitalik for security with a planned HF to arbitrarily freeze peoples assets and is currently making demands that all exchanges halt trades by his decree so investors cannot flee a burning building. He is undermining not only the trust and reputation of the DAO but in Ethereum as well. I expect slow capitulation after a sharp correction when some of the exchanges allow deposits again.
