I'm torn between waiting for an ATV4 and getting a newer ATV3 unit with the bluetooth streaming (or whatever radio it uses). Streaming over my network is glitchy.
If they had folders in the apple tv4 for tvshows, movies, etc. and added a store with gaming options, I'd go out by 5 of them on launch day. Add internet access with safari and surfing capability, I'll grab 3 more.
The first generation of TV had folders. Then Apple decided to "improve" it by getting rid of them for the subsequent generations. Folders for both movies and TV shows worked great by the way. It's one of the features I miss most.
