Of course, something like this is planned for other DACs.
But the whole point of BitShares X is that you can *don't need them*. Saying "can we add oracles?" undersells the genius that is bts X.
That is an interesting answer. We wont need them sure but can we really recreate smart contract functionality which can interface with the real world without them?
I think for Bitshares X if it's going to remain separate from the real world that would be fine but I don't see how you would do something like a prediction market without either a trusted data feed or some sort of trusted decentralized data feed. If you had distributed oracles then we could turn the result of these distributed oracles into a trusted data feed.
So while it might not be for Bitshares X I would think it would be necessary for the MAS DAC.
In any case distributed oracles are interesting http://oracles.li/
