Upgrades to minor revisions of the same major version are free, so if the next release is 1.x, you won't have to pay. Upgrades to the next major version offer a substantial discount; have a look at the upgrade prices for OmniOutliner and OmniGraffle. Don't expect to get anything resembling a date out of Omni, however, unless it is along the lines of "we guarantee it won't be before <some date>."
