Update: 5/9/2014 after watching all the included content, I can say without reservation that the best looking film in 4k is X Men Origins: Wolverine.. Also, I found out from Samsung that the streaming service for 4k films will not be available until the release of the upcoming 2nd UHD pack later this Summer. Not available in this first pack
Also this product (and its future product) only works with Samsung TVs as I said:
No mention of 4K Streaming and selling for the same price as a Nuvola NP-1 Streaming Media Player. Although to be fair, it does come with a 1 TB storage drive (Not sure if it's SSD or not) with some pre-loaded movies.
Also doesn't mention what OS, if any, is included or if it's Google Play ready, or if it's proprietary to Samsung TV's, etc.
