Think about what smart contracts can do but without the risk (Ethereum/DAO hack). This thing can get huge if they do the right marketing!
To clarify, even if I think you meant it that way: NXT 2.0/Ardor, like Nxt 1.0, will not have a "turing-complete" smart contract language. Until today, to my knowledge they are not even planning to add the complete "Automated Transactions" feature (a limited smart contract toolbox) that was integratet into the two other (Nxt-inspired) Java currencies Qora and Burst.
But NXT developers have stated they will "integrate most relevant use cases" of smart contracts. The Phased Transactions feature is one of these use cases, as far as I know.
To the OP question: My expectations for a price are not that high actually, 0.00002 is a reachable short-term goal. Nevertheless, I think just before July 24 price will shoot up a bit, maybe even to 0.00004, bringing NXT back in the top 10. But I may be underestimating it ...
