Don't Wait if You Want More Ports
According to the leaks, the new Apple TV 4K looks like an Apple TV, so that is a good sign that Apple is not changing things up much with the new model in terms of connectivity.
While some users lament the lack of optical audio out with the Apple TV that is on sale, we don't expect to see Apple add in any new connectivity options for the 2020 Apple TV 4K.
If you need optical out for your setup, you will need to invest in an HDMI to Optical splitter and converter, which you can find for about $25.
