Very true. And a search for "Adobe Encore NAB" finds your post first! Then a similar one from 2012.
Encore seems to be the "step-child," when it comes to new features (or making sure that existing one function properly). Not sure why that is, but it might have to do with the Sonic AuthorCore modules in Encore?
Maybe we will all be surprised with some neat stuff from NAB, regarding Encore, but I will not hold my breath.
