I don't think any final decisions have been made, but in case it helps, here's how we've handled stuff like this in the past: once a new version of an app goes into public beta, folks who purchase the old version will get a free update to the new one. Customers that purchased before that point will have the option of upgrading their licenses at a discount.

I'm not on the OmniOutliner team, so I can't predict exactly when they'll be ready for public beta. With that (and the giant grain of salt that it constitutes in mind) I think the time until that happens is measured in months rather than days or weeks.
