Dont forget the aim of XenForo 2.0 is to maintain feature parity with XenForo 1 so add more features to XF1 and XF2 gets delayed! I would expect XF1 to be feature locked now.
The current goal we're working towards is feature parity with XF1, but we already have, and will likely continue to add new features as we see fit. We've mentioned some already, of course.
I would expect 2.1 to be more significant in terms of new features, but 2.0 will have its fair share
