Vitalik has already came out and said that the ecosystem was less mature when the DAO attack happened so no hard fork is possible and that Ethereum is out of his hands. That said, when will the market wake up and realized ETC is now redundant? Does this officially prove that there is no reverse gear on ETH? No rollback should = no need for ETC. It's hard to believe that all this will get swept under the rug but it kind of is at least for the time being. You gonna have your finger at least hovering over the ETC sell button at his point.
