If the DAO is wind down, then these locked Etheruem will be released, that will flood the market with the coins.
... and some of those mEth users will start to get wise that turing complete with a large attack surface isn't wise in general for crypto currencies and make the right decision and sell for btc. I suspect most have latched onto Vitalik and will stay however opening themselves up to future exploits.
What is Hilarious about this is in reality this isn't a Hack at all , and technically theft didn't occur. This "Hacker" simply used the DAO as designed and technically he could sue the miners or developers for freezing his funds that will be taken if a HF occurs. The HF represents a break in the contract that was originally agreed to.
