Remember when we told you the old NVIDIA Shield TV would be getting the new units smarts via firmware update? It's rolling out now as part of an over-the-air patch, TechCrunch has noticed. That means 4K HDR for NVIDIA's GameStream (which lets you broadcast titles from your gaming rig) as well as the newly added Amazon Prime app. (Netflix was already broadcasting in 4K HDR on the box last year.) Of course, if you really want to upgrade your Shield experience, you'll need to pony up for the new game controller. But hey, $60 is a lot cheaper than $200 for the new streaming device itself.
