Its going to be a bit late to do a hardfork once that eth gets dumped. Im noticing some people are still buying atm. I guess they never got the news yet.
TheDao is not ETH. They are betting that ETH will survive whatever happens to the DAO. It is a sensible bet IMHO.
If those hacked eth taht have come out of the dao get dumped then eth will plummet much further than it has already. Eth will still be alive but dumped down to very low prices.
