DEVCON-2 will show many interesting things.
Of coming Dapps I'm waiting for development of Gnosis http://gnosis.pm/ . They are going to start crowdsale in Aug - Sept. Augur is already working on testnet, but Gnosis is getting more support from EF it seems to me. Regretfully almost all releases were delayed after TheDAO mess. As for ETC, if you hold ETH, you should get the same sum in ETC now. I dumped my ETC on the first Poloniex day, have lost a bit, of course... I really don't see any use for ETC but speculations. As to that DAO story there's great post of avsa (Mist author) on Medium https://medium.com/@avsa/the-truth-about-the-fork-fd040c7ca955#.fasfrira7
