You're going to start seeing products touting the next-generation HDMI connection, called 2.1. This is a huge leap forward in terms of bandwidth, capable of up to 8K resolutions and beyond. There will be new cables needed to handle these higher resolutions, called Ultra High Speed, but unless you're buying an 8K TV, you don't need them.
