At the moment there are no plans. There were some attempts to design an "upgrade" that would make the funds recoverable while benefiting the platform, but they had dangerous side effects. A lot of people opposed a targeted recovery fork, for reasons including:
- It's not such a large amount that it's a systemic risk.
- The hack was arguably enabled by negligence; the contract was changed after its last security audit, hacked, changed again and still didn't get a new security audit, and only after that the funds were frozen. Strong incentives to be more careful are probably good. Forking every time somebody's negligent could get messy.
- The DAO hack involve an attack that was new to most people in the community, and even the tutorial code on ethereum.org was vulnerable to similar hacks. These hacks were more in the nature of simple oversights, enabled by overly complicated code. Good auditors would probably have found them.
- The largest loss of funds was to the entity that made the contract (or a related entity anyway). That entity also said they had plenty of other money for their project.
- Most of the remaining losses were to ICOs, who should have gotten competent advice to avoid this contract (given the first hack and lack of audit), and who've demonstrated fundraising ability so could conceivably get bailed out by their own investors.
- Despite heavy criticism from certain quarters about Ethereum's supposed lack of immutability (after the DAO hack), immutability actually is a strong community value. Some people supported the DAO fix on the grounds that it was early days, but feel that the network is more mature now.
