ZCash is tagged as "evaluating" in Exodus roadmap - with this comment: "If the Zcash network remains stable and has continual upgrades it is likely we will support this asset in 2017."
You could also join their Slack[1] to talk directly with a dev. But IMO they are already looking forward to support Monero.
This comment[2] was posted over 8 months ago by the Exodus co-founder but it means that they are already looking on how to integrate Monero to Exodus as soon as possible.
Just so you know, Monero support is our #1 requested feature. It beats out hardware wallet support (#2 requested) by at least 100% - so we're strongly financially incentivized to make it happen.
Unfortunately it's going to be awhile, as we won't release until the UX of Monero feels like every other asset inside of Exodus.
