After reviewing the road map, we've moved things around slightly, so that our next release is what was previously called 5.5.5, now 5.6, the known bugs are planned to be fixed in 5.7, we may or may not address some pending enhancements in 5.8, and then we're still planning on templating being the main or only feature in version 6.
That being said, we're planning to have some more internal discussions on where Publish needs to go, what we need to work on , emphasize, deemphasize, how it fits in with DNN Pro's workflow, etc. This could have an effect on when we feel we need to address templating as a feature.
Let us know if you have any feedback on the directions that you would like to see Publish taken.
Hope that helps,
