Really hard to know. In the past, prior to the CC PS/LR bundle, Adobe would produce a major release of LR every 15-24 months or so. We saw:
- LR1 - 1/07
- LR2 - 7/08
- LR3 - 6/10
- LR4 - 3/12
- LR5 - 6/13
- LR6 - 4/15
On that schedule, we're due a new major release. But in the past, major releases were to generate revenue. Existing users paid only for the upgrade.
Now with CC customers, they don't need major upgrades to generate revenue, and they can dribble out updates and new features whenever they please, and release a major upgrade only when they want a bit of marketing fizz, largely unconnected with features (except for a cosmetic uplift and a new start-up screen).
However, they want to get money out of existing non-CC customers, so need periodic major releases.
That's if they continue a stand-alone product. Previous promises have been along the lines of "we have no plans to discontinue the stand-alone product". Will they suddenly create plans to discontinue it?
That's a long-winded way of saying "I haven't a clue."
