I have yet to see any third party themes or even docs pertaining to them. It's been almost half a year since Roku put out a press release in Februrary (refer to these:
http://www.digitaltrends.com/home-theat ... ce/#!6Vydv &
http://gigaom.com/2014/02/06/roku-to-op ... evelopers/) stating it was opening up theming for third-party devs.
So what happened? Everyday I'm stuck looking at the faux iOS 6 interface that's begging for an update. If it wasn't for the Roku's functionality and the improvements in the TWC app, I would have just built my own HTPC.
